Proplus .msi is a file that is responsible for the installation of Microsoft’s Office Professional program. In fact the proplus.msi is a database for all the files required for the set up, settings, as well as configuration for the Office program on your system. This is a file that is required the first time the program is typically run after the initial installation of the program onto the systems hard drive. There are times when there will be error messages that refer to proplus.msi related problems so the causes as well as possible ways to resolve the problems will be listed below.
The first thing to look at is the cause of these proplus.msi error messages. Most of the time error message that references proplus.msi or any variation of the file is usually stating that the proplus.msi is missing. In most cases the file itself is actually not missing, but in computer terms missing means that a usable version of the proplus.msi file cannot be located.
Often times the file is still present but has been modified, or even moved, from its original place a format which is now creating a problem as the Office program is trying to locate proplus.msi and cannot find a version that will work correctly. As many of these files are located in the registry there have also been reports that proplus.msi error messages can appear if the hard drive, that is where the operating system is located, has the identifier letter changed.
For example, if Windows is installed to drive C and then the drive is renamed Drive D then the Office program might be trying to locate the file with the C in the destination path, which is not where the proplus.msi will be located anymore.
As this problem can be related to the Windows Registry the easiest way to resolve the problem is to download a registry cleaner and run a full system scan to try to fix the issue related to the proplus.msi file on your system. Many times these registry cleaners will quickly find the problem and even fix them for you automatically.
The second option is to insert the original Microsoft Office cd into your systems cd-rom and load the file from the cd. This is another easy way to resolve the proplus.msi, however it can become more difficult if the original disk has been misplaced.
