Rintime Error 91

I have a program that produced a Runtime error 91 ("object variable or with block variable not set") on a computer. I installed VB on the computer to debug the problem locally. Now the problem doesn't occur. There are other computers having this problem running my program. What could installing VB change that would make the program work? I don't want to install VB on all the affected computers. This only seems to happen on Windows 98/ME computers (not all of them...just a few), but I can't be sure it won't happen on others.

Installing VB added whatever files you were missing that your program needs. Make a setup for your program, you can't just copy the exe.

its probably the visual basic runtime files. i dunno.. some programs is required the vb runtimes files to run

No...I made a dependency file to list all the required files for my program. These files are present on all the problematic machines. These are the referenced files, which are the same file versions on the working and not working machines:

Uses1=msvbvm60.dll
Uses2=OLEAUT32.DLL
Uses3=OLEPRO32.DLL
Uses4=ASYCFILT.DLL
Uses5=STDOLE2.TLB
Uses6=COMCAT.DLL
Uses7=scrrun.dll
Uses8=MSCOMCTL.OCX
Uses9=MSCOMCT2.OCX
Uses10=comdlg32.ocx
Uses11=TABCTL32.OCX

Then some/one of them were the wrong versions. That's the only explanation.

you most likely need the ocxs. if you have progress bars, windows common control etc.

you can get the ocx files at 'your windows dir'\system32

I copied the files from the design machine to all the machines I'm using my program on. They're the same files!

try registering all the ocx's... open a dos console and type "regsvr32 c:\somefolder\somefolder\someocx.ocx"

That doesnt work no Windows 98.

i'm pretty sure regsvr works on 98...you probobly typed it wrong.

You're right. I must have mistyped it!

Well this still doesn't seem to fix the problem.

i forget who gave this to me, squirm, volteface...dunno, but its a lil reg hack to make installing dll's and ocx's easier via a right click option, pretty swift anyways
