Devart Forums

I'm tring to reinstall another time the dotConnect for postGree (before to buy a professional version) but back the error:

Devart.Data assembly version 5.0.1506.0 is found in Global Assembly Cache.
This product is compatible with Devart.Data.dll version 5.0.1491.0.

I'm stopped and i can't work.
I need anhelp.

Thank you!

If uninstall process didn't remove the Devart.Data folder in your environment for some reason, try using some file manager (e.g.: https://x-diesel.com/) and navigate to C:\Windows\assembly\GAC_MSIL\ and remove the Devart.Data folder.

The full reinstall with checking environment:
1) uninstall dotConnect for PostgreSQL and other Devart ADO.NET products
2) make sure that there are no Devart.* and policy.*.Devart.* files in the following folders:
* GAC 2.0 (C:\Windows\assembly\GAC_MSIL\)
* GAC 4.0 (C:\Windows\Microsoft.NET\assembly\GAC_MSIL\)
and in this registry key:
* HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\SharedDlls
3) clear the directories:
* \Program Files (x86)\Microsoft Visual Studio __._\Common7\IDE\PrivateAssemblies\Devart\
* \Program Files (x86)\Devart\
* \Program Files (x86)\Common Files\Devart\
* \Documents and Settings\All Users\Devart\EntityDeveloper\
* \Documents and Settings\All Users\Devart\dotConnect\
4) run installation of dotConnect for PostgreSQL via its right click > Run as administrator menu

Does this help?

Sorry i use Windows Server 2008 R2, i don't found the folders
C:\Windows\assembly\GAC_MSIL\
* \Documents and Settings\All Users\Devart\EntityDeveloper\
* \Documents and Settings\All Users\Devart\dotConnect\

Thanks

The folder C:\Windows\assembly\GAC_MSIL\ is system. To access it, either use some file manager (Total Commander, Unreal Commander, etc) or follow walkthrough viewtopic.php?f=1&t=33218#p114802.

Thanks

1. Please specify:
a) the name of the file manager you use when checking the C:\Windows\assembly\GAC_MSIL\ folder
b) send us a screenshot of the file manager window with the subfolders of C:\Windows\assembly\GAC_MSIL\ sorted by name

* GAC 4.0 (C:\Windows\Microsoft.NET\assembly\GAC_MSIL\)
and in this registry key (via Registry Editor):
* HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\SharedDlls
c) clear the directories:

d) run installation of dotConnect for PostgreSQL via its right click > Run as administrator menu
e) clear the bin and obj folders of the existing project (if any), rebuild the project

i sent you an attachment with the screenshot of the path "c:/windows/system", and i do the outhers steps too but nothing...

1. The target folder is "C:\Windows\assembly\GAC_MSIL\" (not "c:/windows/system").
2. We received your email without any attachment, please resend your screenshot.
3. Specify the name of your file manager used when checking the "C:\Windows\assembly\GAC_MSIL\" folder.

Now it's ok, thank'you, last time maybe i wrong some steps...
Best Regards
