Describe the bug
Installing version 0.8.0 while having version 0.7.0 already installed will install in C:\Program Files\ShellAnything 0.7.0 by default.

This is a bug in the design of v0.7.0. It cannot be easily fixed. Upgrading from v0.7.0 is a problem since the default installation directory for 0.7.0 was C:\Program Files\ShellAnything 0.7.0 (with a version number in the path).

To Reproduce
Steps to reproduce the behavior:

1. Install version 0.7.0
2. Install version 0.8.0

Expected behavior
The default installation directory of 0.8.0 should be C:\Program Files\ShellAnything as defined in #101.
