 Now I look closer, I think you're missing something. CreateMute() by itself 
 isn't sufficient. You have to attempt to get it. The code I've used also has 
 a WaitForSingleObject to try to own the mutex:

 hMutex = CreateMutex(sa, FALSE, TEXT(Global\_MSIExecute)); .

 dwError = WaitForSingleObject(hMutex, INFINITE); if (WAIT_OBJECT_0 == 
 dwError) { // You have the mutex therefore MSI isn't installing anything }

 I'll put it this way: I don't understand why you're not passing the string 
 LPCWSTR sczMutexName = LGlobal\\_MSIExecute; into CreateMutex().  Why the 
 StrAllocFormatted call?

 Also it's only locked during the execute sequence, and I don't know how 
 you're testing it.

There was code from NetFxChainer.cpp (CreateNetFxChainer):

ExitOnFailure(hr, failed to allocate memory for mutex name);

// Create the mutex, we initially own

so I was trying that...

it seems nothing is working... I have a MSI running and installing, another MSI

Re: [WiX-users] seeing if a MSI is running using mutex... [P]

2015-01-27 Thread Phil Wilson 
Now I look closer, I think you're missing something. CreateMute() by
itself isn't sufficient. You have to attempt to get it. The code I've
used also has a WaitForSingleObject to try to own the mutex:

hMutex = CreateMutex(sa, FALSE, TEXT(Global\_MSIExecute));
.

dwError = WaitForSingleObject(hMutex, INFINITE);
if (WAIT_OBJECT_0 == dwError)
{
// You have the mutex therefore MSI isn't installing anything
}

 There was code from NetFxChainer.cpp (CreateNetFxChainer):
 hr = StrAllocFormatted(sczName, L%ls_mutex, wzEventName);
 ExitOnFailure(hr, failed to allocate memory for mutex name);

 // Create the mutex, we initially own
 pChainer-hMutex = ::CreateMutex(NULL, TRUE, sczName);

 so I was trying that...

 it seems nothing is working... I have a MSI running and installing, another 
 MSI pops up an error message that another MSI is running but my code isn't 
 working, it isn't getting ERROR_ALREADY_EXISTS

 I'll put it this way: I don't understand why you're not passing the string 
 LPCWSTR sczMutexName = LGlobal\\_MSIExecute; into CreateMutex().  Why the 
 StrAllocFormatted call?

 Also it's only locked during the execute sequence, and I don't know how 
 you're testing it.

 It appears that your CreateMutex isn't passing in the actual MSI mutex
 in sczMutexName .

I could be wrong but I thought MSI stopped using the mutex a couple versions 
ago.
