Description Lluis Sanchez 2014-11-19 03:53:07 UTC
Looks like the XS 5.7 installer is not properly replacing an already installed XS.

This is what Michael reported:

> The Windows installer seems to be corrupt, the XS About dialog is still reporting
> the version as 5.6.2, even though it has the 5.7 buildinfo. Additionally, when I
> try to uninstall it I get an error about GTK# 2.12.22 not being installed

> the 5.7 uninstaller doesn't work. It errors out saying that GTK# 2.12.22 isn't
> installed, even though I apparently have both GTK# 2.12.25 *and* GTK# 2.12.26
> in Add/Remove programs. Additionally, I see both XS 5.6.2 *and* 5.7.

> Okay, I finally got it working by uninstalling all XS and GTK# versions from
> Add/Remove Programs and starting over

Marius, could you take a look at this?
Comment 2 Marius Ungureanu 2014-11-24 11:56:16 UTC
https://bugzilla.xamarin.com/show_bug.cgi?id=17794 was the cause for this.
Comment 3 Prashant manu 2014-11-27 06:11:28 UTC
We will verify this issue once bug 17794 gets fixed.
Comment 4 Marius Ungureanu 2014-11-27 06:24:18 UTC
@Prashant. No. You can verify it with the current installer. try installing 5.7 on top of 5.5.
Comment 5 Marius Ungureanu 2014-11-27 06:25:20 UTC
By 'the cause', I meant that fixing bug 17794 made this one happen. I reopened that one and reverted its fix.
Comment 6 Prashant manu 2014-11-27 06:33:58 UTC
We have checked , XS 5.7 installer is properly replacing an already installed
XS. So closing this issue.

Environment Info:
XS 5.7(build 596)
