Question: I am having trouble viewing .cpc and .djvu files that I've downloaded to my PC

Answer:  If you have downloaded plans and specs to your PC, but they will not open or you receive a blank window with the windows security bar along the top like the image below, try the following.

There are new security features in internet explorer for Windows XP SP2 that blocks active content from running on your PC. To allow the files to be viewed, open your Internet Options menu within Internet Explorer. Go to the Advanced tab and scroll down to the security section. Be sure that the option that says “Allow active content to run in files on My Computer” is checked. This will most likely be un-checked by default.

Another cause could be that the iSqFt image viewer components may be disabled.

Windows XP Service Pack 2 introduced a method for managing addons and browser plugins for Internet Explorer. If the iSqFt image viewer components have been disabled the window will display a red X in the center and sometimes a small gear with a warning symbol will appear in the lower right corner of the window.

Double click on the small gear icon in the bottom corner (or click Tools -> Internet Options -> Programs tab -> Manage Add-ons button) and the Manage Add-ons window will appear. Look for "CPC View ax Control" and "DjVuCtl Class." If they are disabled you will see a window similar to the one below. Make sure they both are enabled by placing the dot next to the Enable option towards the bottom of the window, then hit OK. Once you have enabled them you will need to close out of all the Internet Explorer windows and log back in to the site for the changes to take effect.

Question: When attempting to download drawings I get an appletfile download java IO error message.

Answer: You may receive the following message when attempting to download documents from the website:

This error is caused by a limitation in Java Sun and the length of file paths.  This is most frequently seen when attempting to download drawings located within subfolders on the iSqFt website.  To successfully download the files, you will need to do the following:

• Click "OK" to cancel the download.
• You will need to use Microsoft Virtual Machine and NOT the Sun Java.  To do this, follow these instructions:

  1.     In Internet Explorer go to Tools > Internet Options > Advanced tab.

  2.     Scroll down halfway and ensure Microsoft Virtual Machine is listed and the "JIT compiler" option is checked.

  

  3.  Above Microsoft VM, check for a section called Java Sun.  If this is present, it will need to be unchecked and Internet Explorer will need to be closed and reopened.

  4.  If Microsoft VM is missing, you will need to install it from here: http://www.isqft.com/support/msvm2000/msjavx86.exe. When prompted for File Download… select “Run” or “Open” from the options.  After installation you will be required to reboot.

• Upon logging back in the website you may be prompted with a Security Warning for The Jonathon Group, Inc.  You will need to select "Run" or "Yes" (this various by Operating system and Service Packs installed on your machine).
• Continue back to the project and select the documents for downloading again.
