I suspect a conflict problem with a dll, but I'm not sure how to
identify if this is the problem since R is crashing immediately.
Interestingly, when we start R and do NOT load rgl, but type this
WITHOUT parentheses:
rgl:::.onUnload
We get the same crash.
That will trigger a load of rgl, which will try to load the DLL.
On my laptop I can load rgl just fine, after loading rgl I see:

Can I manually load the DLLs and then load rgl?
Any tips on how to proceed would be appreciated.
I don't have access to Windows 7, but just tried the new R 3.4.2 with
Windows 10, and like you, had no problems.
I'd suggest running update.packages(checkBuilt = TRUE) to make sure
everything is current. If that doesn't fix the problem, you probably
need to run Rgui under a debugger like gdb to identify what the issue is
--- but that's not a trivial thing to do.
If you want to just make random changes hoping that something might
help, updating the graphics driver (or disabling hardware acceleration
if that's something that it can do) could make a difference.
