Questions[chmsee](ubuntu)

I've been a happy user of ChmSee since the awesome 10.10 to view and read my CHM ebooks. Today I tried to install chmsee on my Xubuntu machine, but both apt-get and the Software Center were unable to find the package!

I searched for the package and shockingly it seems that ChmSee is no longer available as of Ubuntu 14.04 Trusty.

Is this true? Why would anyone want to remove such a perfectly usable and functional application?

UPDATE: Since the chmsee package is long gone from the official repos of 14.04-Trusty, what matters more is how can a user of 14.04 install and have this awesome application back.

So I'm updating the question to also ask for a nice way to install and use chmsee on Ubuntu-14.04 Trusty. From 'nice' I mean a way with very few effort and least harm to the system. I don't like adding entire new repositories just to install one app!

I have recently migrated from Windows to Ubuntu.

My current locale shows below output:

    cha@COMPUTER:~$ locale
    LANG=en_IN
    LANGUAGE=en_IN:en
    LC_CTYPE="en_IN"
    LC_NUMERIC="en_IN"

When I am trying to install CHMSee (or any other Application) using Software Center, I am getting below error.

Can someone please help me in resolving this issue? The elaboration would be most appreciated since I am very new to this.

I have chmsee 1.0.7 installed on Ubuntu 10.04. It opens a small chm files (1Mb or 2Mb files) but when I try to open php manual chm file which weights about 10Mb it doesn't open it and doesn't show any error message.

Where is the problem? Has anybody met this problem ever?
