The error is likely to be caused by the following.

1. 8dot3 file name creation has not been enabled.

Please ensure that the Windows 8.3 file notation has been enabled as per the following document.
Software Requirements > CA Service Desk Manager Requirements > 8dot3 name creation

2. Lack of disk space
There is no enough disk space on a HDD where the SDM and temporarily folders are located.
