Hellp Please: Running 2 projects under deferent crystal versions

[stardv]

Please need help.

I have spent 2 days and still did not find a solution. I have 2 differnt web applications. One has reports contracted unde Cr 10 and the other Cr 11. For some reasons i can not make it run together. I can install both version and I see all files of both versions in GAC but only one runs at a time if I unintsall lets say Cr 11 and install 10 then only application running under 10 will run, then if I install 11 application under 11 will only run. So it looks like when I install Cr it overrides some file. I cheked machine.cfg nothing in there. I do not have web.cfg in default web site.

This is the error I get:
[COMException (0x80040154): Class not registered - DTSConnection]
CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocumentClass.Open(Object& DocumentPath, Int32 Options) +0
CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.Open(Object& DocumentPath, Int32 Options) +72
CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.EnsureDocumentIsOpened() +218


I searched entire web, nothinig helpfull.

If anybody knwos how to solve thise issue, i will be very very thankfull

I got some more insight on teh problem that gave me an idea but still no answr. I can set up both web application ussing 2 different crystal versions either on deferent web sistes on the same PC like one on default and the other on some other site and it works and also it works when I set up both of then on other web site than default one. It looks like default site using some regestry or cfg file settings on higher hierarchy level that overrerides web.cfg in virtual dircetory. I cheked machine.cfg what did not seem to have any info for crystal and also I do not have any default web.cfg in default site, at least I do not see it.

Anybody, ideas, please!!!
