I hope this helps, I have run into some 'similar' errors using Crystal Reports 8.5. I ended up writing a program to check the version of particular files that are included in the bootstrap section of the .lst file that is created using Microsoft's package and deployment wizard against those on the client PC that the program would go on. If you find any files on the clients PC that are older in version number than what was included with the bootstrap file, you should recreate the package in the wizard and use a copy of the older version. There is some, but little documentation on MSDN that points to Windows 2000 having a problem(i.e. - security) updating certain files when installing a new application. Hope this helps somewhat, Crystal Reports can be a pain sometimes, I guess we all just have to find our little ways around it. Nick Parker
