Trouble locating actual pdb's on desktop

[fuzzy]

Windows XP/SP3
iSilo for Windows v5.03

When I use windows click data file to open associated application,
it fails to find files. Instead I get an error box in the center of the screen
telling me "c:\Documents" was not found. this usually means that the
operand on the open action of the .pdb was not linked up correctly.

See attachment 1 for the .pdb registration details. See attachment 2
for the error box message. See attachment 3 for iSilo About box.

When I manually execute iSilo.exe its gui interface provides me with a dropdown
menu to open a .pdb file. I'm given a windows explorer like
selection box and can select appropriate files correctly.
It then displays them as expected.

I'm puzzeled at the linkage stuff and wondered if you know
what its supposed to look like. The pathing seems to be
"c:\Program Files\iSilo\iSilo\iSilo.exe" %1


I tried adding double quotes around the %1 as its not seeing the whole target path
but that fails syntax checks on editing.

Any idea how to make windows work as documented?

Put double-quotes around the %1, like this:

"c:\Program Files\iSilo\iSilo\iSilo.exe" "%1"

Make sure that you use the double-quote character (") and not two single-quote characters (') on each end of %1. Two single-quote characters together ('') looks like one double-quote character ("), but they are not equivalent, and so will not work.
