User launches any functionality in Controller which uses the Excel link. User receives the error message.
There are several potential causes for this error message:
Invalid registry entry from third-party software
The Controller Excel-link is checking which version is installed by looking at the uninstall key (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall) in the registry. If a subkey name on the uninstall key contains a trailing space character, the check fails resulting in this error.
Controller registry key from older Controller client version was not successfully uninstalled before the new client version was installed
Locate the registry entry (under the uninstall key) which contains a trailing space. Then rename it so that the key name does not end with a space (‘ ‘) character.
Warning: Always backup registry before editing! Incorrect modifications can cause serious problems to your system.
For example, third party software ‘Altiris Carbon Copy Solution’ leaves an invalid registry key.
1. Launch REGEDIT
2. Navigate to the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
3. Create export from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall structure to a “.REG” file
4. Locate the subkey “Altiris Carbon Copy Solution Agent ”
5. Rename this to “Altiris Carbon Copy Solution Agent”
6. Close Regedit
