I'm having a problem registering other dlls that depend on tibco and ws2_32. I could register them fine prior to putting stunnel on and now they are problematic. Trying regsvr32 returns nothing; not an error or a success. I can successfully install and uninstall this same dll on a different system that does not have Stunnel on it. Windows platform (XP). Has anyone else run into behavior like this and/or does anyone have any suggestions to troubleshoot. I've verified that the dll is not being registered silently by searching the registry. I spoke with a developer who said that Stunnel might be hooking in on my dlls registry attempt and causing it to blow up. Any thoughts? Thank you, Andy
