I have an installshied packaged product existing on the system and it
doesn't have a silent install routine to remove automatically by triggering
a custom action from wix based instaler.So as a workaround, user will be
prompted to uninstall the previous product by checking the relevant registry
entries as follows; But here the the RegistrySearch always returns the
SEARCH2.0 true and it's condition message irrespective of the Version key
value is 1.0 or 2.0.How do i fix this problem? any help?
<Property Id="SEARCH2.0">
<RegistrySearch Id="Reg2.0Search" Type="raw" Root="HKLM"
Key="SOFTWARE\XYZ\Path\2.0\Version" Name="XYZ Product2.0" />
</Property>
<Condition Message="Product 2.0 exists on this system.Uninstall the
software and try again" >
SEARCH2.0 = "2.0"
</Condition>
<Property Id="SEARCH1.0">
<RegistrySearch Id="Reg1.0Search" Type="raw" Root="HKLM"
Key="SOFTWARE\XYZ\Path\1.0\Version" Name="XYZ Product2.0" />
</Property>
<Condition Message="Product 1.0 exists on this system.Uninstall the
software and try again" >
SEARCH1.0 = "1.0"
</Condition>
Thanks
