PMon won't start

Hi, anyone came across this problem? Anytime I try to launch Pmon, I get the following message: "Unable to load support file. Program ending." The uninstall script gives me yet another error, so I cannot even remove and install anew. The error message says "Permission denied" ... When using the TTU 13 installation file, I get the message that CLIv2 13 or higher is not installed, which is not true, it is. I tried to reinstall TTU 15, no success. Please advise, as customer does not allow TD staff to use ViewPoint, and I am now blind to my execution plans. Which is a major pain you-know-where.
