Problem with ExecWait and regedit.exe
I have code like this:

RequestExecutionLevel admin

Section "Install"

    #blah blah blah

    ExecWait "regedit.exe $INSTDIR\Install.reg"

SectionEnd

I know this runs because I get a pop-up asking me if I would like to modify the registry. I click "Yes" when that appears and I get a confirmation saying that the registry has been successfully modified. However, when I actually open the registry to look, I do not see any changes.

When I do this process manually everything works. I double click on "Install.reg" and I get the same pop-up asking me if I would like to modify the registry. I click "Yes" and I get a confirmation saying that the registry has been modified. Then I open the registry and all the changes in the .reg file have been applied. Why is this not working in the NSIS file?

wild guess: you need to put the path to the regfile in quotes

Yup, try something like:

ExecWait '"$SYSDIR\regedit.exe" "$INSTDIR\Install.reg"'

Ideally you should convert the .reg to WriteReg* instructions. There's a util for it on the Wiki IIRC.

I still get the same thing. I get the popup that asks me if I really want to modify the registry. I click "Yes", then I get the pop up that says the registry has been modified. Then when I look at the registry, none of the changes have been applied.

I am trying to delete a bunch of registry keys with this NSIS script.

I originally started with NSIS delete registry instructions and some of the keys were deleted and some of them were not. I also tried using VBS scripts to write to the registry and some of them were working and some of them were not.

I also tried using RunOnce to call a batch script that executes the .reg file. That will also only make some of my registry changes.

Are the keys you are trying to modify/delete in HKEY_LOCAL_MACHINE ???

If so, you will have to make sure that your installer gets elevated (on Vista+) by using RequestExecutionLevel admin and you have to check for Admin rights with the help of UserInfo in your .onInit function!

Also when using NSIS' regsitry functions, you can test the error flag to detect when an operation failed...


Moreover:

On Vista+ all access to 'HKEY_LOCAL_MACHINE\Software\...' will be re-directed 'HKEY_LOCAL_MACHINE\Software\WOW64Node\...' for 32-Bit applications. You have to take this into account when checking the result of your registry operations!
