Live Update

Startbeitrag von stefan.kern am 22.03.2016 22:07

Hi Forum,

I have a question regarding live update.

I have a small windev application (WD20) which I woul like to distribute by internet.
I created a live Update installation package, installed it on a rented dedicated server (1&1) and managed to include the live update into an WB page, where the user must register himself to download the WD software.

I am testing it with 4 pilot users, and everything seems to be ok. One user experiences crashes when the live update wants to install a new version, but it works after the second or third attempt.
I have no idea why ..... the other 3 pilots receive the live updates without any problems.

The goal is to distribute this programm to 100+ customers, and I wonder if live update is a stable product ....

So I would be glad, if other user could give me their experience about the live update and its problems, if there any ....

Thanks for your help



Hi Stefan

as I had written my own system way before pcsoft live update existed, I've never used it myself. However, according to the posts on the french forum (and google translate is your friend here) it seems it is quite sensitive to a lot of things.

Considering that writing your own system is a 2/3 hours job max, I strongly suggest you do so. A basic system can be done like so:
- a text file contains the information about the last update available. This file never change name/url
- the update itself can be put ANYWHERE (on your server or on any other http accessible server)
- a first httprequest to the text file gets the information, including the url for the update itself)
- if current version

Hi Stefan,
I am using live update and it seems to work ok.
The problems I have encountered where:
1. antivirus s/w
2. problems with connections (specially with WIFI)
3. UAC
and in some version - I don't remember which one- my app although it was closed (by the user), it was still running in the background.
Most problems where fixed, after better training of my users (UAC, antivirus) AND
when I stopped installing the application under the programs files directory ..
If you are using a IIs server don't forget to add .net ->text/text in the mime types.

Hi Fabrice and Steven,

thanks for your answers
UAC should be a issue, as all customers of this product are business customer,so I except most users will not have admin rights .....

Fabrice, I did not unserstand the meaning of this sentence:
it is possible to place the wdl in a data directly and update only that.

That means you put the WDL in the data directory of the aplication?
I think I will choose Fabrice way, as at the moment the product is new, and I have only this 4 pilots ....., and better investing a few hours more as having trouble with 100+ customers (hoping to get them :D )

What I also see with Live Update is a kind of latency .... if I start the application nothing happens for 2 or 3 seconds , which is not really good .....

Hi Stefan,

you can split your application in 2 parts:

a launcher (this starts the program, looks for updates and call the component)
the application part (a component *.wdl, your complete appication)

The wdl part can be located anywhere, so in the windows-user- appdata directory.

For the first part you need one time admin rights, for the compoment not. So you must/can update only the second part.

Hi Stefan,

I use the standard out of the box stuff. This works fine for me.

Hi there,

I installed SSL on the server, and Live Update stopped working ..... I could not figure out why ....

So I took .... as recommended by Fabrice ... a few hours and did my own update procedure ....

It is faster, it is more easy to install on the server and I have total control about whats going on.

So I am much more happy with my own solution than with live update.

Best Regards
