Inno Setup  5.1.11
* On Windows 2000 and later, it now uses Windows' own regsvr32.exe to handle DLL registration/unregistration instead of an internal program. This should address errors seen on Windows Vista when registering certain older DLLs. (Windows Vista applies a compatibility fix known as "WRP Mitigation" to regsvr32.exe, which allows it to successfully register DLLs that attempt to write to system registry keys in violation of Windows Resource Protection.)
* Some messages have been added and removed in this version. (View differences in Default.isl)
o New messages: ErrorRegSvr32Failed.
o Removed messages: ErrorRegisterServerMissingExport.
* The uninstall program's version is now 220.127.116.11.
* Minor tweaks.
