Downloading COELIX APEX (version 2.106)
Downloading COELIX APEX is done in three steps:
Step 1 :
You download an installation program of about 35 MB before paying and you proceed to the first part of the installation. A fast Internet connection is recommended.
Step 2 :
If Step 1 is successful, you send your payment via PayPal to order COELIX APEX downloaded.
Step 3 :
Upon receipt of your payment, we will notify you by email how to complete the installation by downloading two other installation programs (about 30 MB each) for the software and six other (about 30 MB each) for the Guide Star Catalogue.
Step 1 (to be completed before you order and pay):
a- Download and save the file COELIXDN1D.EXE in your computer. The dialog box that opens by clicking the download button asks if you want to execute or save the installation program. Answer "Save".
b- Find the installation program COELIXDN1D.EXE and start it by double-clicking on its name, and follow the instructions of this program. By default, the installer suggests to install the software in the folder "C:\COELIX" but you can choose another folder. See here in case of problems.
c- The installer will conclude by indicating whether the installation was successful. If installation is successful, you can continue and go to Step 2 to order COELIX APEX downloaded.

In case of downloading or installation problems
It may happen that the installation program stops and displays an error message saying that the installation file you downloaded is corrupted or there is a virus. The cause of this problem is almost always a file corruption when downloading. A single modified bit on the million of bits is enough to make the file defective.
To address this issue, you can restart the download, but you must absolutely delete each time the temporary Internet files before you do the download. When you download a Web page or file, your browser places a copy of this file in a folder of temporary Internet files. When you download again this file that has the same characteristics ( same URL address, same name, same length, etc.), your browser tries to fetch the copy of the file (possibly defective) in the folder of the temporary files rather than going to download the file from the Internet to save time.
So, always delete the temporary Internet files, close your browser, then restart your browser before downloading again the installation program. Perhaps it will be necessary to try this procedure several times before doing a successful download.
With Microsoft Explorer, you delete the temporary Internet files by clicking the button Delete files in the dialog box that opens from the menu Tools/Internet Options... Do not manually alter the content in the Windows folder.
