In Citrix environment (x64) – get below error when trying to add queue onto Citrix server (Windows 7 OS) in this instance.
In this case, all other Citrix servers were fine, apart from this one which had below error.
This is caused by a dll file missing within the spool folder.
To resolve the issue; followed below steps.
You can request the hotfix if you really want to, or even wait for Windows 7 SP1, but the "workaround" is so simple that there’s no point in trying the other options:
- Go to the C:\Windows\system32\ directory and find the file "mscms.dll"
- Copy that file to:
- C:\windows\system32\spool\drivers\x64\3\ if you are using 64-bit Windows 7
- C:\windows\system32\spool\drivers\w32x86\3\ if you are using 32-bit Windows
**This hotfix, then re-adds the missing .dll file which can become corrupted sometimes.
