Installer Detected Incompatible Version

I am trying to install dotConnect for Oracle version 6.30.160 and I am getting an incompatible version found error. The message says:

Devart.Data assembly version 5.0.242.0 is found in Global Assembly Cache. This product is compatible with Devart.Data.dll version 5.0.260.0.

However, when I use the gacutil.exe tool, there are no references to any Devart product. In addition, I checked the assembly folder in the Windows directory and the GAC folders in the Microsoft.NET folder and uninstalled or removed anything related to Devart. I then scanned the entire c: drive and removed all Devart folders. I also scanned the registry and removed all references to Devart.

Devart data providers use a common assembly (Devart.Data.dll), so it is necessary to install compatible providers versions. The compatible versions have the same release date.

Please make sure that there are no Devart.* and policy.*.Devart.* files in the %WinDir%\assembly\GAC_MSIL\ folder and restart your computer. Try installing 6.30.160 again. Please notify us about the results.

Hi

I have the same problem, but:
If I try to unistall the old versions with gacutil

Code: Select all

gacutil /u "Devart.Data,Version=5.0.93.0,culture=neutral,PublicKeyToken=09af7300eec23701"

It say that I have dependent references

Code: Select all

SCHEME:   ID:   DESCRIPTION :

gacutil /uf cannot force uninstall if dependent reference is windows installer

How can I remove the old libraries?

We recommend you to uninstall the previous version of dotConnect for Oracle using the Devart uninstaller: %ProgramFiles%\Devart\dotConnect\Oracle\Uninstall\unins000.exe. You can also run it via Start Menu > All Programs > Devart dotConnect for Oracle > Uninstall dotConnect for Oracle.

By the way, I was able to unistall Devart.Data.dll with gacutil.exe from Visual Studio Command Prompt (2010) using gacutil /u. Maybe it makes sense to uninstall the Devart.Data.Oracle.* assemblies from your GAC first, then remove Devart.Data.Oracle.dll, then delete Devart.Data.dll. But we recommend using our uninstaller.

How do you uninstall the policy files in command line?

You can uninstall the policy files by using gacutil.exe. Gacutil is supplied with the SDK. Run cmd and execute the following command:
gacutil.exe /u policy.6.60.Devart.Data.Oracle.

I have the same problem with no solution until now.

I've uninstalled all Devart products, cleaned GAC, cleaned Windows Registry and same error on install new Devart Version.

I've tried everything that are saying in forums and so on.

The error persist:
"Devart.Data assembly version 5.0.272.0 is found in Global Assembly Cache.
This product is compatible with Devart.Data.dll version 5.0.431.0."

Please make sure that:
1. You have deleted all assemblies with name, starting with "Devart", from GAC;
2. You have deleted all assemblies from the folders c:\Program Files (x86)\Common Files\Devart\ and d:\Program Files (x86)\Devart\

None of this folders exists. I'm trying to do this from days and days =[

I've tried to install every version since 2011 until now and the same error... I'm almost reinstalling Windows.

Please check the folder "C:\Windows\assembly\GAC_MSIL\". Delete all folders containing the word 'Devart' in their names.
Windows Explorer can't see this folder because it has a shell extension which makes the GAC look not like another folder. To delete folders which contain the word 'Devart' in their names you can use Total Comander or FAR Manager. You can also use cmd. Execute the following commands:

Code: Select all

cd C:\Windows\assembly\GAC_MSIL\ - go to GAC folder
dir/p - page-by-page display of folder content.

write down the names of all folders containing the word 'Devart' in their names and then delete them. For example

Code: Select all

rd Devart.Data
