Affected versions

• 77.0a1(2020-04-24)

Affected platforms

• Windows 7x86

Steps to reproduce

1. Download the targeted Firefox Stub Installer.
2. Run Firefox Stub Installer.
3. Click "Yes" on the UAC Prompt.

Expected result

• The Installation starts.

Actual result

• An error message is displayed saying that “Firefox Nightly Installer has stopped working”

Regression range

• Don’t think this is a regression since it is part of the new feature.

Additional notes

• I used a clean environment for this (all mozilla appdata and registries were emptied before running the stub installer)
• A Stub Installer 74 version works fine.
• See the attached screenshot with the error message.

The issue was verified fixed using the latest Fx 77.0a1.
The stub installer now correctly installs Firefox, no longer hanging or crashing on Windows 7 x64 and x32.
