Try this, change strProcName and strProcPath in lines 6 & 7 Also change the message in line 17 to suit.
Some applications, such as UltraVNC run 2 processes, so for something like
that, change the 0 in line 16
This has only been tested on WinXP SP3, so YMMV on later OSs.
Quick and nasty, but gets round the issue of the users being able to
delete the lock file.
I use PrimalScript for all my scripting and the handiest thing I use it
for is to compile scripts in exe's so that the code can't be changed to
increase the number, but I'm sure google would throw up some alternatives.

Subject: RE: Limit the amount of times an application can be

Only problem with that is permissions.
If ?I? am launching the app, I am creating the lock file, which isn?t
secure. If someone is clever, or even in an accidental situation this can
be bypassed?

Use a batchfile to create a ?.lock? file and check for the existence of
that file and if it exists, have the batch file exit.

We have one application that is absolute resource hog. Unfortunately the
users will open it over and over again, usually bringing the system to a
crawl. It has been very difficult to train them to only open it once.
Anyone have any ideas on how we could limit the amount of times it is
opened?
