This has been done for Firefox / Thunderbird and I thought Seamonkey as well. It should contain the following... this will launch the 7-zip stub without elevation on Vista and then NSIS will request elevation. <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="1.0.0.0" processorArchitecture="X86" name="7zS.sfx.exe" type="win32"></assemblyIdentity> <description>7-Zip Self-extracting Archive v4.42</description> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="X86" publicKeyToken="6595b64144ccf1df" language="*"></assemblyIdentity> </dependentAssembly> </dependency> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"><security><requestedPrivileges><requestedExecutionLevel level="asInvoker" uiAccess="false"></requestedExecutionLevel></requestedPrivileges></security> </trustInfo> </assembly>

Frank, could I get you to review this? To see the change to the binary you'll need reshacker ( http://www.angusj.com/resourcehacker/ ) and the addition is resource 24. I'll also attach the binary.

Comment on attachment 352499 [details] [diff] [review] patch Oh right, I forgot to change the manifest to match the new installer code. Patch looks good and seems to work fine, r+.

Frank, shall I land this on both trunk and 1.9.1?

Yeah, do it that way.
