We have noticed that FastCAM can encounter troubles with Windows 7 and Windows 8 machines with the User Account Control (UAC) is switched on.
The problem with this is that temporary files necessary to run FastCAM, which are usually saved to your FastCAM Folder, are instead placed into your Virtual Store Folder on Windows. This can cause a variety of bugs, and also make it impossible to save and retrieve old path settings for both FastCAM and FastNEST.
In case you were wondering this is what UAC actually does:
Which is to say, not a whole lot, outside of annoying pop-ups.
So there are two things you can do to stop this happening on your FastCAM.
Firstly, Disable your UAC:
Secondly, clear your Virtual Store of any FastCAM Folders.
1. Navigate to the folder:
For 64 bit:
C:\Users\<USERNAME>\AppData\Local\VirtualStore\Program Files (x86)\FastCAM\
For 32 bit:
(Where USERNAME is the name of the user you are currently logged in as)
2. Locate the FastCAM Folder (If you have other FastCAM products here you can ignore them, you are just after the FastCAM Folder)
3. Delete the folder completely.
4. Change the Permissions on the Main FastCAM Folder ( The folder from Step (1) ), and make sure it has Read & Write privileges for your level of user (for instance, USER level). Here is a little link on how to change a folder's permissions:
This SHOULD disable the Virtual store for FastCAM on your PC.
However we have had cases where this has not been sufficient. The solution to this is to Move your FastCAM Folder from C:\Program Files\FastCAM\ or C:\Program Files (x86)\FastCAM\ to just C:\FastCAM\. Then clear up your virtual store.
Once this is all done you should attempt to clear local temporary files:
