Hi Guys,
I have a problem with registry. My application uses several GPL tools
and one of them is GhostScript.
So, installer checks the registry, maybe user already has the same
version of GS
<Property Id="GS_64">
<RegistrySearch Id="gs_dll"
Root="HKLM"
Key="SOFTWARE\GPL Ghostscript\9.06"
Name="GS_DLL"
Type="file"
Win64="yes" />
</Property>
Otherwise these registry keya will be created
<Component Id="add_gs_64" Directory="TARGETDIR"
Guid="{65207ECA-9C47-4ddc-AABB-137B04010CD2}" Win64="yes">
<Condition>GS_64 = ""</Condition>
<RegistryKey Root="HKLM"
Key="SOFTWARE\GPL Ghostscript\9.06">
<RegistryValue Id="GS_DLL_64"
Type="string"
Name="GS_DLL"
Value="[localBinGSx64]gsdll64.dll"/>
</RegistryKey>
<RegistryKey Root="HKLM"
Key="SOFTWARE\GPL Ghostscript\9.06">
<RegistryValue Id="GS_LIB_64"
Type="string"
Name="GS_LIB"
Value="[localBinGSx64]"/>
</RegistryKey>
</Component>
It works fine until I update installer v.N-1 to v.N:
1. v.N checks registry - key exists
2. v.N-1 deletes key created during the installation
3. v.N doesn't create a registry keys however these keys not exist anymore
So, how can I check the registry after v.N-1 will be uninstalled?

Kind Regards,
Maxim
