Rbloomberg Crash Fixed

[Roberts, Timothy]

I have recently become an R user, and have the latest release installed
on an XPSP2 machine. I kept getting an "R-gui front-end encountered a
problem" every time I ran blpConnect() . For all of the users that have
been having this issue, it is probably caused by RDCOMClient. Fixing the
problem was a matter of just allowing network administrative rights on
my machine, so that RDCOMClient could function properly. I haven't had
any issues since! Thanks to Robert Sams and Ana Nelson for helping me
troubleshoot this.

You are talking about this problem:
https://stat.ethz.ch/pipermail/r-sig-finance/2006q3/001029.html ?

Sounds great, this is really helpful, but I cannot "apply" this
workaround at work, they will never give me admin rights for anything.
And I guess I am not alone with this problem. If you can locate the
problem, perhaps the RDCOMClient people could then fix it?

If the problem is Windows security permissions, then the answer will
probably be in the Windows security settings.  No,w, it is possible that
some set of permissions less than "admin rights" would still suffice.  I
suggest talking to your information security folks, and having them work
with you to make the applications work together.

Hi,

Given that most problems with security under Windows come from running as admin and that most security experts suggest that you don't then surely fixing the problem with the code is the right solution; not getting "enough" admin rights to make it work.

Regarding David's point, it depends on how much admin access is required by
the COM API itself. If the API requires you to be an admin then there's not
much that RDCOMClient can do about that (other than handle the situation
more gracefully than crashing - maybe it's possible to check for admin
rights first).

This thread:
https://stat.ethz.ch/pipermail/r-help/2007-October/142255.html
would seem to suggest that rcom *might* not have the same issue.

Obviously for both adoption and security reasons it's best for
RBloomberg/RDCOMClient to require the minimum possible level of access. I'll
try and take a look at this issue from RBloomberg's perspective and see if
there's something that can be done.

If anyone has any advice/experience that might be relevant I'd be very happy
to hear it, either in this thread or offline.
