update download error message

mted558 · 07-30-2011, 08:26 AM

Every time I try to update Calibre I get an error message that says
"The installer has encountered an unexpected error installing this package. This may indicate a problem with the installer package" error 2503 then same message and error 2502. I get the same message if I try to uninstall Calibre as well. So how do I fix it?

That often means a corrupt download. Have you tried downloading from the alternate site in case you have a bad cacehed copy somewhere.

I tried downloading from different sites, tried uninstalling which it won't let me do and even tried downloading an earlier version and still getting the same error message.

Standard solutions to this problem:
1)Do NOT use a download manager.
2)Disable your antivirus (only if you use an official source)

I don't use a download manager. Tried disabling my antivirus program then tried the download and still the same error message. I really like using this program but not sure what I'm going to do now if I can't even get it installed.

I got similar errors when upgrading to 8.10. I was downloading to a networked drive. What solved it for me was to download to a drive actually in my machine.

(I hadn't had that error prior to then....and I haven't upgrades FROM 8.10 yet. so YMMV)

Thanks for the suggestion. I'm already downloading to a local drive so I don't think that's my issue. But I tried downloading to my external drive just in case and still got the same issue. Anyone else have any suggestions???

What version of Windows (and SP) are you using?
XPpro SP3 8.12 works
W7hp SP1 8.12 works

mted558 · 07-31-2011, 05:36 PM

I'm using Windows 7 Home Premium SP1

The only thing I did different, was I used the download I had grabbed with XP for the XP update.
I use Firefox 5 ALL platforms

mted558 · 07-31-2011, 07:27 PM

how do i get an XP formatted download? and I use Chrome. Could that be an issue?

the XP download is just a WINDOWS download.

Does chrome have a anti-whatever_might_be _bad_for_your_computer toolbar?

something is messing up your Calibre install download.

BTW I always keep the last 2 known good update downloads, 'just in case' I need to roll back

PeterT · 07-31-2011, 09:36 PM

lol.. I tend to keep all the downloads

Once in a while I head through D:\Downloads and clean up (but not that often).

Anything is possible, try IE or Firefox.

mted558 · 07-31-2011, 09:58 PM

i actually tried going back to some previous downloads but got the same message with each one. I tried using Firefox and IE but still the same thing. I've probably screwed everything up now by trying to download over and over again and deleting, etc.etc...... I did a search on my computer and just deleted everything associated with calibre hoping that would solve the problem but when I tried to download I got the same error. I know it has to be something so easy that I'm missing but for the life of me I can't figure it out. And I'm a prime example of have a little knowledge and being dangerous because it makes me feel like I know what I'm doing but apparently I don't.
