Applies To:
  • CitectSCADA 5.20, 5.21 Service Pack

Summary:
When I try to use the Tag Import / Export / Linking features I get an error message like:  

Unable to Import Tags. The operation has failed. 

Or Citect crashes with an error like: 

Citect Project Editor : CTEDIT32.EXE - Application Error The exception unknown software exception (0xe06d7363) occurred in the application at location 0x77e87e08."

 

Solution:
These errors can occur if Citect 5.20 or 5.21 is installed in one directory and another copy or version is installed in a different directory.  When Citect is installed, it registers COM objects that it uses with its OPC server and for Tag Import / Export / Linking.  After that, these features will no longer work for the other installations of Citect since the objects will be registered to the latest Citect installation directory only.  If the copy of Citect that you want to use OPC or Tag Import features with does not work, the easiest way to fix this is to re-install that copy of Citect.  This will re-register the objects to that Citect directory. If you cannot do that, or that did not fix it, you can manually correct the path in the registry settings using Windows RegEdit.exe.

Fix all of these keys that exist in your registry (some may not exist):
