Wondering if anyone has tried reversing a vsix install.
I have a custom action that runs on install, and the uninstall version which
runs on uninstall. The install works perfectly, but the uninstall fails for
apparently no reason.
<CustomAction Id="InstallTemplates"
Directory="VerDir"
Execute="commit"
Impersonate="yes"
ExeCommand='"[...snip...]vsixinstaller.exe"
"[INSTALLDIR]\DerpTemplates.vsix" /q'/>
<CustomAction Id="UninstallTemplates"
Directory="VerDir"
Execute="commit"
Impersonate="yes"
ExeCommand='"[...snip...]vsixinstaller.exe"
/u:DerpTemplates.aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee'/>
<InstallExecuteSequence>
<Custom Action="InstallTemplates"
Before="InstallFinalize">
<![CDATA[NOT Installed]]>
</Custom>
<Custom Action="UninstallTemplates"
Before="InstallFinalize">
<![CDATA[Installed AND NOT UPGRADINGPRODUCTCODE]]>
</Custom>
</InstallExecuteSequence>
(they've been shortened down a bit of course).
The weird this is that although the uninstall fails, I have confirmed that the
command is 100% correct. I ran the uninstall while logging. In the log, I
copied out the command that the custom action reported it was going to execute.
I then pasted that into a command shell and ran it. It worked without any
issue.
I tried to turn off error checking in the custom action by adding
'Return="ignore"' but, while the uninstall didn't fail, the custom action still
didn't uninstall my templates.
Has anyone experience in this? Why would my custom action fail in the
installer, however succeed when the command is executed outside of the MSI?
TIA.
