The explanation is the same as for PD Howler 9.6 or other programs powered by Project Dogwaffle.
Find where PD Howler 10 is
installed in Steam, and fix this problem for good
(1) Most likely, your Steam
installation on Windows lives in the 32-bit tree
of Program Files on the C: drive:
(2) Inside of the Steam folder, find
the steamapps sub-folder:
(3) Digging deeper, open
the common sub-folder:
Keep digging, we're not
there yet: You may have many games here, we
had just a few. We had uninstalled Howler 9.6 but the folder might still be there, albeit empty.
(4) Howler 10 shows as a folder named
PD Howler 10 (note: although not likely, it might slightly change over time for future updates)
So here we are in the folder of the PD Howler 10
installation under Steam. You'll want to
look for the file named dogwaffle.exe
(5) You'll need to scroll down to find it, most likely, unless you have a high resolution screen and a tall window on it.
(6) Did you find it? This is the program file from which PD Howler is launched: dogwaffle.exe
You can in fact try to run it from here, or create a shortcut to your desktop for easy launch outside of Steam too, if you want.
If we run it right now, it will
likely still fail with the "Unexpected error; quitting" error, because
we haven't run it as Administrator yet.
(7) So, try right-clicking, and
(8) use Run as Administrator.
You need to do this just once,
if prior or other versions of Dogwaffle had been installed, or if the
installer was not raised to Administrator level. This is in order to
self-register a bunch of files for its use.
[ 8 ] Note that if you still run
Howler 9.6 or other versions of Dogwaffle (such as PD Particles, PD
Artist,...) you might have the problem again when switching back and
forth between different installations. If you prefer to run this one as
Administrator every time automatically, use the Properties option at the
bottom of that right-click menu.
After you've done this once, it should launch fine without the need to run as Administrator again.
1. Select the Properties view from the right-click context menu.
2. In the Properties view, select the Compatibility tab
3. check the box for 'Run this program as an administrator'
4. click OK
From here on, whenever this program is launched, it
will re-register its dependencies for its use. If you keep other
versions of Dogwaffle on the same system, you may want to make that
canghe for them too.
Happy howling! and
thanks for waffling.
