Status: RESOLVED DUPLICATE of bug 759615

(Toolkit :: Application Update, defect)

Description

[Simona Badau, Desktop QA]

Attachment: Nightly icon in the Programs and Features list

Mozilla/5.0 (Windows NT 6.0; WOW64; rv:15.0) Gecko/15.0 Firefox/15.0a1

After updating the second newest Nightly build from May 30th(2012-05-30-14-43-27-mozilla-central/) I noticed that it looked uninstalled in the programs list in Control Panel. When clicking on the Nightly icon in the programs list the error message is received: 

"An error occurred while trying to uninstall Nightly 15.0a1. It may have already been uninstalled. 

Would you like to remove Nightly 15.0a1 from the Programs and Features list?"

Before Nightly updated to the build from May 31st I managed to reproduce this issue also on Windows 7 (in this case I updated the latest available build from May 29th to the build from May 30th). Currently I can only reproduce this on Windows Vista x64 using the latest available build from May 30th.

Steps to reproduce:
1. Download the latest Nightly build from May 30th and install it.
2. Check for updates and click on the Restart button.

Expected results:
The update is successfully done and the Nightly icon is displayed in the Programs and Features list.

Actual results:
Nightly seems to be uninstalled from the Programs and Features list.
