Adodb connection ошибка 800a0e7a

So I am going back to a project I created in College, so I can transfer it to PHP. I orginally coded it in ASP Classic.

I am on Windows 8 and running Access 2013.

I am currently getting the following error

ADODB.Connection error ‘800a0e7a’
Provider cannot be found. It may not be properly installed.
/PROJECT!Better/verifyuser.asp, line 11

and this is my connection string code.

Dim vPath, pPath, Conn

vPath = ".dbComic.accdb"
pPath = Server.MapPath( vPath )

objConn = "PROVIDER=Microsoft.ACE.OLEDB.12.0;DATA SOURCE=" & pPath & ";"
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.Open objConn

any help that you can provide would be awesome!

edit: I already have the enable 32-bit applications in IIS Activated

  • I’m coding a ruby script that has to write data in an existing Access Database. With following code I don’t manage to make a connection with the database: 

    require 'win32ole'
    connection = WIN32OLE.new('ADODB.Connection')
    connection.Open('Provider=Microsoft.ACE.OLEDB.12.0;Data Source=d:ex1_student.mdb')

    Error: 800A0E7A — «Provider cannot be found. It may not be properly installed.» 

    Access 2010 32-bit and Windows 10 64-bit OS. I did find questions with the same error, but the solutions doesn’t seem to apply for me.

Hey guys….can someone help me please
i’m running an asp application on a windows 7 home premium (64 bit)
and i keep getting this error over and over ADODB.Connection error ‘800a0e7a’ Provider cannot be found. It may not be properly installed. (line 68)

here is the code :

dim fname, lname, minitial, email, phone, dob, grade
dim CardNumber, PWord, reminder, fullname, fixm
dim ActiveP, Resident, FriendsExp, prob, holdcard
dim fnx, lnx, mnx, rs, pIndex, Fdate, DobDate
dim adding
dim fdatedata, dobdatedata
dim Name, City, State, Contacted, lastEmailed, SecondToLastEmailed, Comments
dim MuseumPasses, Title

pIndex = Request.Form(«pIndex»)
contacted = Request.Form(«iActive»)
MuseumPasses = Request.Form(«iResident»)
LastEmailed = Request.Form(«iFriendsExDate»)
name = Request.Form(«iTitle»)
email = Request.Form(«iEmail»)
SecondToLastEmailed = Request.Form(«iDOB»)
Comments = Request.Form(«iCardNumber»)
City = Request.Form(«iPassword»)
State = Request.Form(«iReminder»)
adding = request.form («adding»)

Title = Request.Form («Title»)
prob = name
prob = Replace(prob, » «, » «)
holdcard = request.form(«holdcard»)

if NOT IsValidEmail(email) Then
response.write «Bad Email Address, not updated»
response.end
end if

if len(state) > 2 then

state = left(state,2)
end if
if request.form(«Submit») = «Delete Prospect Information» then
response.write «<center><FORM Action=’mlremove.asp’ Method=’POST’ Name=’ATA’>»
response.write «Are you sure you want to delete: » & name & » » & email & «?»
response.write «<P><input type=’submit’ name=’yes’ value=’yes’>&nbsp;&nbsp;&nbsp;»
response.write «<input type=’submit’ name=’no’ value=’no’>»
response.write «<input type=’hidden’ name=’indexer’ value=» & pIndex & «>»
Response.write «</form></center>»
response.end
end if

if MuseumPasses = 1 then
MuseumPasses = myTrue
else
MuseumPasses = myFalse
end if

if Contacted = 1 then
Contacted = myTrue
else
Contacted = myFalse
end if

set dbconn = Server.CreateObject(«ADODB.Connection»)
dbconn.ConnectionString = strConn
dbconn.Open (thats the line where i get the error)

IF request.Form(«update») <> «update» then

set rs = Server.CreateObject(«ADODB.recordset»)
rs.CursorLocation = 3
sql = «SELECT name, email FROM MailList WHERE email = ‘» & email & «‘;»
rs.open sql, dbconn
if rs.RecordCount <> 0 then
fnx = rs(«name»)
rs.close
set rs = nothing
dbconn.close
set dbconn = nothing
response.redirect «mlAdd.asp?bd=6&per=» & escape(prob) & «&cn=» & email
end if
rs.close
set rs = nothing
sql=»»

the connection string that im using to connect to my Microsot Sql Server 2012 database is the following :

strConn=»Provider=SQLNCLI;Server=*****;Database=** ***;Trusted_Connection=yes;»

So i was thinking probably the provider is not correct ?
I need help guysssssssssssssss pleaseeeeeeeeeeeee thats an end of study project for my school

This is often caused by attempting to connect to an Access database
using OLE-DB (e.g. Provider=Microsoft.Jet.OLEDB.3.51;) without having JET
components installed.

Microsoft.Jet.OLEDB.3.51 is a very old version, and we have Microsoft.Jet.OLEDB.4.0 installed on our servers, in order to fix the error, please update

Provider=Microsoft.Jet.OLEDB.3.51  to Provider=Microsoft.Jet.OLEDB.4.0 from your database connection string.

Solution 1

Check the site’s Application Pool in IIS / Application Pools / YourPool / Advanced Settings :

  • Advanced / Enable 32-Bit Applications: True

There’s some anecdotal evidence to suggest you do this too:

  • Managed Pipeline Mode : Classic

Solution 2

You should use the provider available in your machine.

  1. Goto Control Panel
  2. Goto Administrator Tools
  3. Goto Data Sources (ODBC)
  4. Click the «Drivers» tab.
  5. Do you see something called «SQL Server Native Client»?

enter image description here

See the attached screen shot. Here my provider will be SQLNCLI11.0

Solution 3

I got the same issue and It got solved by installing Oracle 11g client in my machine..

I have not installed any excclusive drivers for it. I am using windows7 with 64 bit. Interestignly, when I navigate into the path Start > Settings > Control Panel > Administrative Tools > DataSources(ODBC) > Drivers. I found only SQL server in it

Please Finc the attachment below for the same

Solution 4

A couple of suggestions

The ACE driver isn’t installed by default. It’s also a 64 bit driver, so it might be worth disabling 32bit in your app pool. I’ve known 64 bit drivers not work when 32 bit is enabled.(eg the ISAPI filter which connects IIS to Tomcat).

The older JET driver is 32bit. It is included by default. If you could save a copy of your database as a .mdb file then using the JET driver might be a workaround

Solution 5

Have you got the driver installed? If you go into Start > Settings > Control Panel > Administrative Tools and click the Data Sources, then select the Drivers tab your driver info should be registered there.

Failing that it may be easier to simply set up a DSN connection to test with.

You can define multiple connection strings of course and set-up a ‘mode’ for working on different machines.

Also there’s ConnectionStrings.com.

Just to further this, I found this thread on another site.

  • Are you saying that Oracle 11g client can connect to a JET or an ACE database? FYI There are two ODBC managers in 64 bit windows, the 64 bit version you find in Control Panel, and the 32 bit version which you will find at C:WindowsSysWOW64odbcad32.exe

  • I guess for ACE database it will not be sufficient. But to connect Oracle database Oracle 11g client will be sufficient. I got «ADODB.Connection error» while am trying to connect Oracle DB

  • Thanks, Vinayak Prabha, you solved my problem! I had Provider=SQLNCLI but when I looked at my drivers, I found I had two versions installed, 10.0 and 11.0. Changing to Provider=SQLNCLI11.0 fixed the problem

  • Enable 32-Bit Application is required but Pipeline Mode can be Integrated. This is how my application runs so requests go through ASP.NET security and HttpModules.

  • Remember that this is for ODBC drivers. If you’re using OLE DB drivers then you may be running into the issues relating to @JamesMcCormack’s post above.

  • I’m going to have to get this tattooed to my hand. I keep forgetting in my senility!
