Note that if you set permissions to a folder with PermissionEx element, the permissions are set recursively for all descendants. This means if your TEMP folder exists and is full of folders/files, the installation time will increase...

Subject: Re: [WiX-users] How to reference a system environment variable? I already figured out, I need to specify Directory element and not DirectoryRef element, which I tried before. If somebody interested, there is code to do that: <Property Id="SYSTEM_TEMP_FOLDER"> <RegistrySearch Id="SystemTempFolder" Key="SYSTEM\CurrentControlSet\Control\Session Manager\Environment" Root="HKLM" Type="directory" Name="TEMP" /> </Property> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="SYSTEM_TEMP_FOLDER"> <Component Id="SystemTempFolder" KeyPath="yes" Permanent="yes" Guid="*"> <CreateFolder> <PermissionEx User="NameOfUser" GenericRead="yes" GenericWrite="yes" xmlns="http://schemas.microsoft.com/wix/UtilExtension"; /> </CreateFolder> </Component> </Directory> ...

Hi all, I have a question about setting permissions on SYSTEM temp environment directory: If I will read information from registry about location of SYSTEM TEMP, how can I use it to set permissions? Should I write custom actions to do that? Can I reuse PermissionEx element from Util extensions?

As horrible as it may be, I've been reading system environment values out of SYSTEM\CurrentControlSet\Control\Session Manager\Environment for about 4 years now and there haven't been any support issues (both XP and Vista). I don't use this for setting values though. I use the normal Environment WiX element.
