Strange problem with RegRead

[autoking]

Hi. I want to test if a uninstall string exists, for that I use this code:

RegRead('HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall','')
If @error = 1 Then Msgbox(0, 'Error', 'Key "HKLMSoftwarecould not be found.')

It works, but I need to check if this exists:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall{D6AB1F5B-FED6-49A9-9747-327BD28FB3C7}

it won't read the registry path, even it does exists, I don't think regread can handle this: { }

any idea how to solve this problem :S?

you may need administrative previleges to access to HKEY_LOCAL_MACHINE, check the @error

Hi, autoking. I find that you get mixed results when just trying to get to a sub-key under Uninstall, so I usually try to enum one of that standard values inside that particular key (usually DisplayName or DisplayVersion). For example, the following works for me on XP and Win7:

$var = RegRead("HKLMSOFTWAREMicrosoftWindowsCurrentVersionUninstall{003BFBBD-6C67-419E-A24D-0DCAFC3A5249}", "DisplayVersion")
MsgBox(0, "", $var)

it's not because of admin rights .

I just tried you example, but it won't get the path :S

$reg = regread("HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall{EE3A5B79-C147-4BD9-952A-E894298C2ACA}" , "")

If @Error > 0 Then
msgbox(0, '' , "Key does not exist")
Else
msgbox(0, '' , "Key exists")
EndIf

The idea here is to check for the existence of the key, not the value. Even if you do get a -1 result for an uninitialized "Default" value (I am curious as to what version of Windows you got that result from), you still know that the key exists. You wouldn't get a -1 or a -2 result if the key did not exist.

If this is a 64 bit OS, you may need to change it to HKLM64, instead of HKLM, or use #AutoIt3Wrapper_UseX64=n, or a combination of these, to get it to find the correct key

[autoking]

I tried with HKLM64 it works. but #AutoIt3Wrapper_UseX64=n didn't have any effect
