This is the error number for Could not access JavaScript runtime for custom action (you'll see this if you have MSI logging enabled). Normally this is solved with:

regsvr32 jscript.dll

This doesn't always work on x64 machines, because there are multiple regsvr32 files on a 64-bit machine in the SysWow64 (64 bit translation layer). Try:

cd c:\Windows\SysWow64
regsvr32 jscript.dll
