Title
"Cannot load the DLL xpSLS.dll" error during database backup -
Description
Was able to remotely deploy LiteSpeed but when trying to backup database, an error occured with this error:
"Cannot load the DLL xpSLS.dll"
-
Cause
Unsuccessful remote deploy installation. The log file from the host running remote deploy shows:
Information: Thread 14 : MSI Command Line: INSTALLDIR="C:\Program Files\Quest Software\LiteSpeed\SQL Server" LICENSEKEY="<LICENSE_KEY>" SITEMSG="<SITE_MESSAGE>)" LICENSETYPE="LICENSE" SILENTPHASE=0 REBOOT=ReallySurpress
Variable: Thread 14 : Install Return Code : 1625
Error: Thread 14 : Installer Error 1625 : This installation is forbidden by system policy. Contact your system administrator.

Resolution
WORKAROUND 1:
Address the windows permission error on their end then remotely deploy LiteSpeed again. May need to contact system administrator for some help.WORKAROUND 2:
Login to the target server then manually install or deploy LiteSpeed. -
Additional Information
Manual deploy/installation for a lot of servers would be extremely laborious. If deploying LiteSpeed in many servers, workaround 1 is highly suggested.
