Hi Brian, we have the same problem with BackupReader.
We wrapp the data compare functionality we need in a dll, which will be used our asp.net application.
The dll using SDK is compiled for x86, with recommended options for the pree and post-build events (http://www.red-gate.com/supportcenter/C ... wledgebase
With the SQL Toolkit 6.0 we had no problems with backup reader dll and the above scenario.
Now with Comparison SDK 8.1 we have an exception "Cannot load Backup Reader dll!" on the code line:
IList<IBackupSet> backupSets = backupDB.GetBackupSets(files, passwords);
It doesn't help also to compile our asp.net application for x86.
Have you any ideas, how to get off of the exception?
