Hi. I've installed a 3CX Server yesterday (free version for the moment, but I'll buy it later if everything goes well). Right now, I have the build 4128 installed and I'm trying to do the update to 4287 using the start menu shortcut. Everytime I launch the update, I get an error... Windows Script Host ------------------------- Script: C:\Program Files\3CX PhoneSystem\updates\Update 4CXPhonesystem to version 5.1.4287\update.4287.vbs Line: 35 Char: 51 Error: Permission denied Code: 800A0046 Source: Microsoft VBScript runtime error I've read other threads here and on the internet about similar errors. I've created a rule in my antivirus not so scan the entire 3CX install folder (C:\Program Files\3CX PhoneSystem\) including its subfolders and the file "update.4287.vbs". I've also added rights (all except total control) for 2 users (IUSR_.... and IWAM_....) on the 3CX folder (I've read about it on another forum, don't remember wich one). I also have reinstalled vbscript runtime environement and rebooted the server after that. I still get the error. I wonder what I need to do to be able to update finally. Here are my infos: Windows 2003 Server Enterprise R2 Version 5.1.4128.0 free edition VBScript libraries 5.6 This is my main problem with the software, other than that, I'm totaly satisfied, except for problems outside the place where the server is, but I didn't search on this yet. Thanks.
