My intention is to set the INSTALLDIR to a path retrieved from a Registry Key, as well as appending subfolders. First, I set up a System Search for: - Folder path, as specified by registry entry - Registry Root: HKEY_LOCAL_MACHINE - Registry Key: SOFTWARE\Company\CompanyFolder - Registry Value: InstallPath - I also select the "Search 64-bit portion of the Registry" I store the value into property SDIR64, and select "Store the value in the property and use the property in an Install Condition" For the Condition, I simply enter the property SDIR64, and the Message is logging INSTALLDIR and SDIR64 properties. Then, I create a Custom Action (New Set Directory) and name it SetSDIR64InstDir Action ------ Directory Name: INSTALLDIR Directory Value: [SDIR64]subfolder1\subfolder2 Return Processing: Synchronous (check exit code) Execution Scheduling: Always execute MSI Type number: 35 Sequence -------- Install Exec Sequence: After CostFinalize . . . When I run the MSI, the message box appears and there are no values displayed for INSTALLDIR or SDIR64. I click ok, and the wizard quits. From the MSI log, it appears that AppSearch did indeed find the path from the registry key. It does some expansion for the 32 bit folder naming convention, but all in all, yielded a value.

Why does AppSearch seem to pull the correct value, but the Property created (SDIR64) does not reflect the value retrieved? Is there a step or scope issue I may be overlooking? Any help is appreciated, thanks much! ... View more
