Error 2755 and MSI

I was surprised getting strange error, while trying to run an MSI produced with VS2005
The error was saying:

.The system cannot open the device specified. The installer has encountered an unexpected error installing this package.This may indicate a problem with this package.The error code is 2755.

Finally, Google says that this error is encountered when the install image is placed on an encrypted volume. After moving the installer to non encrypted volume , the error disappear
