Today, I was prompted by Libre Office to download an update. I clicked on the link which led me to the Libre Office website, from where I downloaded a 201MB file named LibO_3.5.5_Win_x86_install_multi.man . However when I double click on it, I get the dreaded "Windows can't open this file" message. What to do now?

Using Win 7 64

Strangely, previous updates did not have that hiccup.

Did you check the integrity of the downloaded file using the MD5 checksum or other checksums? Did you try to open it with Administrator privileges?

if possible, tell us the mirror you downloaded from. It is using a wrong mimetype that causes your browser to rename the file. The URL is not download.documentfoundation.org/... since that will just pick a mirror for you. Please check your download history for the actual mirror, so we can notify it.

Finally, 9 days after, I downloaded the update again, and this time, the install went ahead normally. Thanks for help.

It would be a good idea to change this forum to a less obscure interface.

The Libreoffice packages for Windows are in a MSI-format these days. Your LibO_3.5.5_Win_x86_install_multi.man might have been accidentally renamed to .man extension during save; try to rename the package to LibO_3.5.5_Win_x86_install_multi.msi (which is the name used in the download site).

@Spring_Chicken: using a checksum, you can verify the integrity of the file you've downloaded. See the Wikipedia page on on checksums.

To check it, you need two things:

• the correct checksum for the individual file to download, to compare it with the cecksum of the file you've downloaded;
• a software to calculate the checksum.

The checksums for all the LO downloads are available on the "Info" page of every download. Take care to get the checksum for the specific file you've downloaded - OS, LO version, Language, Program or Help pack.

To calculate the checksum for the file you've downloaded, there's a lot of freeware software around - check the mentioned Wikipedia article for links.

If you encounter problems installing a program, make sure to:

• verify the integrity of the download (as explained above);
• have sufficient privileges to start the installation (you may need to start the installation as admin user);
• have read and write access to the downloaded file. If you choose "Run downloaded file" or something like that directly from the browser's download dialogue, installation may fail if the browser saves the download read-only. So, you should choose "Save locally" or "Save on local disk" in your browser's download dialogue to save the download, and then open the download directory with Windows Explorer and run the file from there.

Sorry tohuwawohu ; I had not seen your comment, due to the obscure interface of this forum. I don't know what is a checksum and I never used it. I deleted my download and downloaded it again... but I have the same message.
