Insane RegRead Problem

[Spiderkeys]

This is supposed to be one of this simplest scripts around,

I want RegRead to read variables and return them to me in a msgbox.


First I copy an example for my template from https://autohotkey.com/docs/commands/RegRead.htm

Code: Select all

RegRead, OutputVar, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion, ProgramFilesDir
MsgBox, Program files are in: %OutputVar%

Result is perfect, "Program files are in: C:\Program Files"

So, I could think i could just copy and paste the above and change the locations and let it read any value from the registry so my script goes as

Code: Select all

RegRead, OutputVar, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion, ProgramFilesDir
MsgBox, Program files are in: %OutputVar%

RegRead, OutputVar, HKEY_LOCAL_MACHINE\SOFTWARE\Dropbox\Client, Version
MsgBox, Dropbox version is: %OutputVar%

RegRead, OutputVar, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{FC4A0E2E-0CD3-11E6-B80E-005056951CAD}, DisplayVersion
MsgBox, Evernote Display Version is: %OutputVar%

The first one (original one) shows excepted result
second entry shows no value (Blank)
third entry also shows no value (Blank)

It doesn't matter where I go, everywhere returns a blank value except that example template.

Did you verify that the Reg path is right? I don't have a HKLM\SOFTWARE\Dropbox path in my Registry and I've got Dropbox.

Double checked, tripled checked, mine are correct, I find a variable of interest, I go to the key where the value is, right-click, copy key name, paste it in the script, the paste the string value after the comma

Other than that, I'm using Windows 10 if thats the issue...

Check the ErrorLevel being returned from RegRead (add ErrLev=%ErrorLevel% to your MsgBox commands). My guess is that first one will be 0 and the other two will be 1. Next trick is to figure out why.

are you using the 64bit version of ahk?

[Spiderkeys]

Yes, anyway it turns out those keys no longer existed after a reboot, so obviously, problem solved...
