I recently installed some programs on a windows 7 64-bit computer. The installation appear successful (no error mesage). However neither the program folders nor the programs can be found on the hard drive. If I try to re-install the programs, the system tells me they are already installed. The computer also runs Comodo firewall (free), Avast anti-virus (free) and Malwarebytes Anti-Malware. I tried disabling comodo and re-installing the program - no difference!
Any idea?
Thanks
