What Windows or OS are you installing to or using SM on?
Installer Error Code 2755 can be caused by a range of problems, most usually:
- Make sure that the directory or folder you are installing into allows writing to that directory or folder.
To resolve this problem, change the permissions on the Installer folder. The permissions on the Installer folder should be Everyone - Read Administrators - Full System - Full.
- On some Windows 7 systems, you may need to run the installer as an administrator.
Would be good to know more about the system you are working with, for sure, as installer problems are actually VERY rarely seen, and install problems are normally very few and far between.
