Strange problem with RegRead

7 posts in this topic

#1 ·  Posted (edited)

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


Heroes, there is no such thing

One day I'll discover what IE.au3 has of special for so many users using it.
C'mon there's InetRead and WinHTTP, way better

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)

$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


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.
