Hi Charlie,

I've attached a picture of what happens when I type run into the windows
DOS command window. Run is not a valid command in Windows 10 and I'm not
sure it ever has been.  What version of windows is on your laptop?
Type ver in your DOS command window to find out...

The only situation that I can think of in which "run thumbs" would work
in the DOS command window is if you have a program called run.exe in the
same folder and thumbs is used as the parameter.

Please type dir *.exe into the DOS command window and tell us what exe
files get listed.


> Hi Andy...   The app works in cmd windows if I type 'run thumbs'.  I get the error message if I try to do the same thing in dbase command.  So not working in dbase at all.
> I am not sure if thumbs is dos although maybe.  It is a very old windows program possibly.  But the same thing happens no matter what app I try to run in dbase.
> When I tested with the msgbox the directory that came back was dbasewin which is my dbase directory.
> Tomorrow when I get to work I am going to compare paths in environment.  Long time ago I was having problems with perl and might have accidently deleted some paths that had been there.  This could have been broken a long time as I don't remember using any 'run' commands for a while on this laptop.  I use them every day on my work computer.

>>> This is an example of the very simple code that works on other computers.  For some reason it does not work on my laptop in dbase which indicates it is a problem on this computer, not with code that I have written.
>>> It does work in the command prompt in windows if you type in ' run thumbs'.  So I am trying to figure out why it does not work in a menu in dbase or a pushbutton on this specific computer, but does work in the same menu or pushbutton in dbase on other computers?
>>> I have gone into paths in windows environment and tried to work with that with no positive results.  I am wondering if possibly something in dbase desktop properties could fix this but not sure.
>>> I am just reaching out to see if anyone has run into this before and if they know of a solution.
>>> Hope this gives a clearer picture.
