Another error resolving post.
Here's the error:
Import has encountered an error and has been canceled. Your system has been restored to its original state. Import has been canceled because the ISV.Config file could not be imported. Check that the file format is valid.
Also connecting to the CRM Workflow Manager will probably not work. This error message is thrown:
The specified Microsoft CRM server is not responding. This might happen if it is currently unavailable, it is not a Microsoft CRM server, or you are not a valid user. For more information, contact your system administrator.This is -probably- being caused by incorrect settings in the srf files. Check this by going to the CRM website folder (C:\inetpub\wwwroot\) and browse to the folder MSCRMServices. In that folder open the file bizusersdl.srf in notepad. In that file you do see a folder. Try to browse to that folder by copying the folder name and paste it in Windows Explorer. You'll see that the name is in short format like: c:\progra~1\micros~3\.... This format does not match the location of the crm folder.
I have been able to solve these errors by repairing CRM. Go to the control panel, click add/remove programs and select Microsoft CRM. Then choose for 'Repair'. Another option would be to follow the steps in kb859798 (partner source required). That KB article describes how to reset the .srf mapping in step 8.
