Yes 32 bit Windows wont have 64 bit registry. not good. Note that you can access Registry.Registry32 from a 64-bit app if necessary. If you want to set in on an the executable itself instead of just one shortcut, open the properties and check the “Run as administrator” box at the bottom of the
Remember that if you compile to "AnyCPU" and run on x64, your inherently using Registry64. To troubleshoot this issue, we really need the source code to reproduce the problem, so that we can investigate the issue in house.

Join them; it only takes a minute: Sign up Cannot read Registry entry in C++ up vote 2 down vote favorite I have a registry entry I can't seem to read But in my code I have hard coded the following string "SOFTWARE\MyCompany\MyApp" I thought that WOW64 could translate correctly from "SOFTWARE\MyCompany\MyApp" to SOFTWARE\Wow6432Node\MyCompany\MyApp. Empty lines or not? mentions GetUserName and GetUserNameEx. –CodesInChaos Oct 10 '14 at 12:36 I found this: experts-exchange.com/Programming/Languages/Visual_Basic/… Maybe it helps you to find a solution when LoggedOnSAMUser is not present. –blacai Oct
My guess is that it is some sort of permission or access problem, but I have not been able to find the magic words to make it work. Any suggestions? When I try to read the node, the system returns no handle: winapi::regOpenKey(#HKEY_LOCAL_MACHINE, @'SOFTWARE\Microsoft\Dynamics\6.0\Setup\HelpServer', #KEY_READ);) If I try to read the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dynamics\6.0\Setup that has a property with the same name If possible, change your platform target to x64 and retry.
because reading has no danger. I created a visual basic 2005 setup project that creates a context (right-click) menu on IE.

You cannot post replies to polls. http://kelcours.com/cannot-read/cannot-read-registry-key-value-debug-error-0.html Again, the installer occurred as expected. Solve the problem by requesting that you read from the 64 bit view of the registry, by way of the RegistryView enumeration. Run the setup again as an administrator9.

All rights reserved. Subkeys of the keys in this table inherit the parent key's behavior unless otherwise specified. Directly accessing internal windows registry keys is usually not a good idea. Not the answer you're looking for?
Either check that the correct key is there too, or compile in 64-bit. Thanks.

Not sure why I couldn't read the 64 bit registry key from a 32 bit application. –user3308131 Oct 10 '14 at 13:05 add a comment| up vote 0 down vote Almost
if I rename the 64bit key out of the way, leaving the 32bit key, the code fails to return the 64bit key.. When I try to run my .Net 32 bit app, surprise to see it can read the keys on registry and find correctly the directories in Program Files. The puzzling thing is the code does work on a different server that is also 2008, but is R2. You don't need to switch to x64.
However, access to Registry.64 is NOT permitted from a 32-bit app!
