Sucks!! My customer encountered this issue while trying to launch published apps(e.g.IFS, SingleView, etc) via citrix after resumption from her annual leave.

Investigation shows that the MSLicensing path in her Windows 7 worksation is corrupted and should be corrected;

Resolution:

1. Run Command Prompt as an Administrator
2. Type regedit then press Enter
3. Backup registry incase of unforseen circumstance
4. Locate Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing
5. Right Click MSLicensing folder then select delete command
6. Confirm Delete and restarted customer's workstation

Launch application(s) again
