When attempting to install Citect on a PC which has no C:\ drive (e.g. Terminal Services), the installer will fail and the following error will be displayed on screen:

"Error 1327. Invalid Drive: C:\"

You will need to create a temporary C:\ drive so that the installer can complete. You can do this in 2 ways:

1. Map a network drive in Windows. For more information, click here.
2. Use the subst command in Windows. For more information, click here.

Developers have confirmed that this is a problem with the existing product installer. This issue is being considered for review for future releases.
