i Access Solutions - error loading java module

Late September I started a thread regarding a MSGSOCK007 on our CEO's
laptop. That issue has been resolved. However I was also having issues on
my desktop that aren't resolved. I was getting ready for vacation so I
backburnered it till now.

Here's the situation. System i 520, V7R1, fairly well up-to-date on PTFs.
My desktop is Win 7 pro 64-bit, on a domain.

The only way I can start I Access is by double-clicking the acsbundle.jar
file. If I double-click acslaunch_win-64.exe I see a flash of a black
screen blink at me, then nothing. If I try to run acslaunch_win-64.exe in
a command prompt I get "Error loading java module." Same if I try as
Administrator.

File extension .hod is assigned to acslaunch_win-64.exe. When I
double-click an .hod file, I see a flash of a black screen blink at me,
then nothing. If I try it in a command prompt I get "Error loading java
module." Same if I try as Administrator.

The getting started text has a bunch of trouble-shooting regarding this,
like setting up a JAVA_HOME environment variable, etc, none of which
worked. Rebooted several times to no avail. All this was yesterday, my
first day back from vacation.

Since it works just fine on my laptop (also Win 7 Pro 64-bit), I decided to
wait till today, bring my laptop in, and compare settings side by side. (I
initially just copied the entire folder structure from my laptop to my
desktop, so all those files are the same.)

The environment variable for javapath is the same on both. There is no
JAVA_HOME environment variable on either. The java version is the same on
both. The Help/about shows the exact same java information on both. The
only difference I can think of is the laptop is not joined to the domain.

I know Jim Oberholtzer says he just double-clicks the acsbundle.jar file,
but I want to be able to double-click the .hod files.

Suggestions? Hopefully something obvious.
