ISRegSrv.dll is absolutely necessary ??

[hashimoto]

Hello experts,

ISRegSrv.dll is absolutely necessary fo IS10.5 ?
There is no ISregSrv.dll in my pc, so it causes many errors ?

Error messages are
"Error 1904 C:\....\....(file name).. faild to register
HRESULT -2147220474 "

I think that ISRegSrv.dll is the InstallShield DLL that is to register and unregister files on the target system.
Plz give me your advice !

best regards,
hashimoto

According to the InstallShield 10.5 Help Library page "HRESULT Values for Windows Installer Run-Time Errors", that error means "Executable file extension, but not actually an executable". Does that describe any of the files you've marked as self-registering?

Yes!
The problem is resolved.

I marked some files self-registering...
Thanks so much. It's very helpful fo me! :)
