Program Installation

[fattyfatpants]

Hello all, I have yet another quandry...

I have developed 2 applications, both of which use VB6 SP6 for the front end, Access 2003 as the back end, and Crystal Reports 9 Developer as the reporting engine with the CRViewer control displaying the reports from within VB...Both are being installed on Win XP Pro SP1 boxes...

I installed my first application and everything works 100% beautiful including running the reports; however, I installed my second application and everything seemed to be working 100% until I tried to run the reports...my app just crashed...so I started the first program I installed and went to run the reports and it just crashed also...being the wonderfully intelligent person I am I took notice that both of the apps crashed at the exact same spot; when I closed the report viewer...so I uninstalled both apps and re-installed the first one, tried it out and voila it worked perfectly, and then before I installed the second app I converted the Setup.lst to a text file and went in and deleted all of the references to Crystal Decisions\Crystal Reports, converted the file back to a .lst and then re-installed the second app...both work perfectly now...

My question is what just happened here?? I mean, can I not install more than one application that utilizes the CRViewer and all of Crystals support files on the same machine?? Even though both apps work 100% I need to know what went wrong...This is driving me crazy...Sorry for making this such a long post

>app just crashed

What do you have for error handling in this program??

Ex. On Error Goto...

I have an On Error Go To statement in all of my sub routines and methods...It's not that it gave me a run-time error or anything like that, it just stopped responding much like when your IE or any other app stops responding...then I got the dialog to send an error report or not

I would recommend using something like dependency walker to determine the DLL dependencies for both applications then see if both are installing some common ones. If that is the case then it is probably the cause of your problem.
