The Cancel Retry Paradox

Yesterday when I attempted to install the AutoCAD 2011 service pack (er, I mean “update”), I encountered the classic UI paradox where you’re forced to choose from a set of equally undesirable choices, this time with a bonus.

I received error 1321. My choices were to retry or cancel. If I chose to retry, I got the same error again. If I chose to cancel, I got a bonus question: it asked whether I really wanted to cancel. I had to lie and choose yes, otherwise I would be trapped in an infinite loop.

The error message indicated that the cause was the installer’s inability to write to the original installation media. I’m not sure why it wanted to write to the original media. The only way to apply the service pack was to uninstall AutoCAD, create a temporary copy of the original media with write permission enabled for the copy, then reinstall AutoCAD from the copy and apply the service pack afterward.

Missing Language Pack DWG File Repair

I wrote before about corrupt text causing bogus “Missing Language Pack” warnings in AutoCAD. That case prompted me to write a file repair utility. However, since the case appeared to be isolated, I never released the utility to the public.

The problem has been rearing its ugly head again, so I decided to dust off the original code and release it. The repair utility is now available on the freebies page (look for CleanLanguage.zip) for AutoCAD 2007 and later versions of AutoCAD. I have not tested any recent cases, so I can’t be sure it is the same problem. If you try the utility, please report your results by leaving a comment here.

Free Confidentiality Agreements

It’s not too often that lawyers give away their work, but Gene Quinn of IPWatchdog.com is doing just that by providing some free sample confidentiality agreements. If you can afford to pay an attorney for simple agreements like this, more power to you; otherwise you may want to grab these free agreements while you can. There is of course a disclaimer, but thankfully it’s short and simple just like the agreements.

Deelip Menezes Predicts a Cloudy Future

I had the good fortune of hearing Deelip Menezes deliver the keynote address at the Bricsys 2010 Conference in person. If you missed it, check out the video now at the Bricsys web site. The question and answer session after the speech is an excellent harbinger of the discussions to come if Deelip is correct in his prediction about CAD on the cloud.

Using VC 7 build tools in Visual Studio 2010

Developers, if you use VC Build Hook and/or need the same capability in Visual Studio 2010, please let Microsoft know by voting for a fix. I’ve written before (and here) about the problem. I think it is possible to hack a third party solution, but by far the best solution is for Microsoft to add back the ability to produce ANSI response files in service pack 1.
