Error “CLR20r3” caused by crystal report

In the blog entry of “Cashcard transaction history read software”, I have developed an software to read out the transaction history log, however when I created an install package and installed on another computer which has the OS Windows 7 32 bits, encountered error “CLR20r3”, the application cannot start at all.

Did search on the internet, tried to install the “Microsoft .NET Framework 4.5 “, cannot solve the problem, then found out the software used the crystal report, needs to install the Crystal report package, “Crystal Reports Basic for VS 2008 Service Pack”, it seems this problem resolved.

This “CLR20r3” may be caused by many other reasons, crystal report maybe one of them.
