Cannot Create File ".tmp". Access is Denied

[ueberyak]

I have a virtual machine that I share with a coworker. We have some scripts saved to a network drive that we run from the VM. When I log in to the VM and run our macros, everything works as expected. When my coworker tries to launch a macro, he gets the following error.

Cannot create file "C:\Program Files (x86)\Macro Scheduler 15\20221007132808msrt1a.tmp". Access is denied.

In the past he has run these jobs without trouble, so I'm not sure what has changed recently. Is this as simple as it states, and he somehow lost access to C:\Program Files (x86)\Macro Scheduler 15? As always, any help is greatly appreciated.
