HKLM "bitbreitenunabhängig" .NET Framework Hi, ich lege ein paar Pfade in der Registry ab. Auf einem 64-Bit BS l?uft meine Anwendung normalerweise mit 64-Bit, aber unter HKLM \ Software abgelegt. Offenbar scheint es aber f?r 32-Bit Apps den Unterkey Wow6432Node zu geben. Deswegen findet sie das Programm nicht.

a lot of changes in our clients. I tried to search these CLSID in the registry and found that they are existing in both the 64 bits and 32 bits section (under Wow6432Node). I know that Windows copies some registry keys from one section to the other, but I'm not sure in which direction one?). It seems that it may change the way registration informations are stored in the registry. Also, sometimes, we get the "Class is not registered" error. If we register again our version must be registered with the 64-bit version (%windir% \ sytem32). Willy. know and that registry. register They are two different hives - a 32-bit and a 64-bit.

Discussions Image (1) Online (1) Hi Nick, Yes, you may config this by using the registry key below: [HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Microsoft \ Windows NT \ CurrentVersion \ Image File Execution Options \ yourapp.exe] REG_DWORD "Wow64" = 0x00000001 This however is not the recommended way of doing this. It is preferred that step using corflags.exe. Can you tell me why you would prefer an config file / registry opention? Thanks.

into the process space of the client application (64bit). 32bit components are registered to HKEY_CLASSES_ROOT \ WOW64 \ CLSID in a 64bit system while 64bit components are registered to HKEY_CLASSES_ROOT \ CLSID. Because our 64bit client cannot find the component with CLSID or ProgID under HKEY_CLASSES_ROOT \ CLSID registry key, the error 0154(Class not registered) is thrown. To workaround this 32bit versus 64bit the server registration on a 64-bit OS, or you have a problem related to registry virtualization on this OS. What OS version are you running this on? What version of can see several possible points where this could fail. My first candidate would be the registry reflection. The 32 bit service would register under the WOW6432Node. I haven't been able to verify if the 64 CoCreateInstanceEx is smart enough to check that node if it doesn't find the server in the standard registry, or if somehow the 32 bit server gets registered under the standard registry keys, by some OS magic. Anyway if the registry was not kept up to date as the server registers and de-registers itself you

such as assembly company copyright ) use some global constant from visual studio or OS's registry data. If you want them to reflect your own custom values, you can open the understand where the default values come from in my existing VB2005. The value $registeredorganization$ from registry should be the key in this case. However, the PC I use to evaluate VB2008 think I may skip to provide the value so VB2008 fails to retrieve it from registry. Now my question is shifted to how I can fill value in $registeredorganization$. Thanks again Wong Thanks for your reply James, Yes, I think those values should be maintained in registry, however, so far I haven't found clear documentation on this. I'll consult some the Microsoft on-line document #310441, I found the way to modify company information in registry. I tried to input value in RegisteredOrganization under HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion and Wong Thanks for your followup James. That's great.

For instance, it bit us in an installer which did some registry settings stuff, and ended up with Windows-On-Windows issues (http: / / www.thescripts.com / forum to do with that data is pretty hard. For example, if you write to the registry from a 32 bit app, then try to read back the same key in a 64 bit app, you'll get totally different data. This is due to the Wow6432Node, which does some tricky things that you just have to know about. This bit us http: / / www.coversant.com / blogs / cmullins This is the result of the "virtualization" of the registry, done when running "legacy" 32 bit interactive applications under WOW64. 64 bit applications never run virtualized, nor do 32 or 64 bit services and drivers
