A client of mine is just putting in Secure Gateway 3.0 with WI4.6 (and PNA). I noticed that they didn’t have Session Reliability enabled and I was going to set it up for them. I noticed that they didn’t have any hotfixes for Secure Gateway 3.0 (which is a no-no since you’ll have problems connecting in with newer ICA Clients 9.2+ when using Session Reliability). Citrix fixed the issue with the hotfix SGE300W003 (CTX110661), but that hotfix was later superceded by SGE300W008 – CTX114059. So you go off and download CTX114059 and attempt to apply it to your Secure Gateway 3.0 setup. During the installation the hotfix stops and tries to restart the Secure Gateway service. However, you receive an Error 1920 from Windows Installer stating that it’s unable to start the Secure Gateway Service. The reason for this error is that the Secure Gateway hotfix is dependent upon a Microsoft Visual C++ Runtime DLL (MSVCR71.DLL). If it’s unable to find this DLL in System32 or in the rest of the system path, then the service fails to start. To resolve this issue, simply locate a copy of MSVCR71.DLL on your Secure Gateway system (or on another similar platform server) and copy it into your System32 folder. Then click Retry on the Windows Installer dialog and voila! you’re done. Enjoy!
