i had that problem. and read all posts here. none worked. then by mistake i read of error 11708 posted by the MSI. that one said that the decompression folder had to long name. so i took the install file, moved it to a folder with shorter name, unrared it with winrar and ran the bootstrap.exe file. and woula.
worked fine.

so god bless alcohole 140% becouse it was there i found the error.
enjoy
