Perl Command Line Interpreter has stopped working (windows vista)

Hi All

I have this program that I think is developed using Perl (from the error message i am getting).
When I try to run the program (.exe) it tells me that "Perl Command Line Interpreter has stopped working".
This program used to work but now it doesnt. I am running windows vista.

many thanks

Do you have perl installed?  Try typing "perl -v" at a prompt.

no i dont have perl installed, it a stand alone .exe program.
it really strange, because it was working and then suddenly broke.

Did you ever have perl installed?  Is this program trying to use perl?

Do you have the source code for this program?

i am not sure if i have perl installed, i have been installing some pdf apps that might have installed perl at the same time, but i am not sure.

also i think this .exe might be trying to use perl, but also i am not sure, it just a stand alone .exe file that i could just run at any time.

and i dont have the source for the .exe it was given to me as is.

i tried with installing activeperl, but still the same problem.
i was doing some testing with htmldoc and PDFcamp (PDF Writer) + DocConverter COM. So I installed those programs. but then i uninstalled them... and i think those could have been the cause but i am not sure.

I could possibly attach the program i am running, it quite small...
please let me know, thanks

after some investigation, apparently p2x561.dll and perl58 are both perl interpreters and i think the program i am running uses p2x561.dll which i have on my machine, but somehow windows vista is telling the program to use perl58.dll as the interpreter but perl58.dll is not the compatible with the program.

so, how do i set the default perl interpreter on my windows vista.

The default perl interpreter will be perl.exe, usually located at c:\perl\bin on windows systems.  You don't tell the program which dll's to use, the program specifies which dll's it'll use.

If you are missing a required library, you should try re-installing the program.

oh ok, i get what you saying...  did some further testing... it seems like if p2x561.dll doesnt exist the program doesnt run at all (no error either), when p2x561.dll exists, it looks for per58.dll, but it never required this perl58.dll to run the program until recently so i made perl58.dll available and then it throws the error: "Perl Command Line Interpreter has stopped working".

and also i dont have the install files, it just a standalone .exe that i copy and paste.

anyways, i am going to leave it for now, maybe it will come right again some other.

thanks for you assistance.
