WIX 3: Using HEAT for Visual Basic 6 COM Dlls

I am using WIX 3. I used heat to create a wxs file for VB6 dll. Msi creates without errors, and the installation is also successful.

Everything seems fine, and I can successfully execute the component from the VB client.

However, if I call the component from the ASP page, I get 0x800401f3.

If instead of the installer I use self-registration (regsvr32), both work fine.

I made a difference in the registry to find out what is the difference between self-registration (regsvr32) and the installer, and I see the following

  • All entries in the HKCR match - everything is fine here.
  • regsvr32 adds entries to HKLM, and the installer does not apply to HKLM

I am wondering if this is a problem, or am I completely mistaken.

MSDN ( http://msdn.microsoft.com/en-us/library/ms694355(VS.85).aspx ) mentions that registry entries are required in HKLM, wondering what I'm missing here.

Below is a file created by heat.

            </Component>
        </DirectoryRef>

</Wix>

Update. Using the "SelfReg" parameter for the file makes the ASP client also work. I read from other posts that this cannot be used. Can someone tell me what to do?

In order for the installer to place entries in HKLM, the installation must be marked as perMachine, by default it is perUser, as shown below.

<Package InstallScope="perMachine" InstallerVersion="200" Languages="1033" Compressed="yes" SummaryCodepage="1252" />

Once this is done, entries are included in HKCR as well as HKLM.

I hope someone finds this useful, took me for 6 hours.
