I was planning on installing FastSCP on my Windows 7 workstation so I started up the installation file (veeam_fastscp_3.0.1.266.exe) till this error message suddenly showed up:

Too bad, and when you press OK in this screen it stops the installation.

No worries, I found a workaround to install this one relatively easy (supported or unsupported).

When you start the installation file once again you see the following windows preceding the error message:

This message actually shows the original installation executable extracts its installation files to a temporary directory.

So when the error-message pops op again, just don’t press OK and leave it there for a moment.

In the meantime you open your Windows Explorer and you open the following folder: “C:\Users\YourUserName\AppData\Local\Temp\” and you look for a directory that is named somewhat like “IXP000.TMP”.

In this directory you will find the following files from which you will start the FastSCPSetup executable to initiate the installation and install FastSCP without problems.

NOTE: In case of missing or not properly working functionality within FastSCP after installing you will still have to wait for a proper Windows 7 version. Remember: this is a -somewhat- dirty workaround. It works for me, but it is not supported and  might as well not work for you.
