Hell Dan, thank you for the reply. So first of all let me make it clear what I'm struggling for. I would like to be able to run my installer as if it was the first time for any version. So say that I'm doing launching the version 1.00.00 the first time, then - ON THE SAME MACHINE - I install the 1.01.00 I do not want to get any remove/modify dialogue. To do this as I I told you I launch the setup.exe installer through setup.bat which launches the command. start .\Setup.exe /V" REINSTALLMODE=voums REINSTALL=ALL" Is this the right way to do what I need?!? That being said as I told you I have to be able to uninstall the latest installed version from the Programs and features tab in the control panel. To do that I have copied the guid from Installation Information---->General Information---->Product Code ---> {4E513BB8-74A0-4626-A967-EFB85EAE9759} You can see that in the attached Scr1.jpg picture. Then -as you can see in the Scr2.jpg picture- I pasted this code in Media---->Releases---->Setup Tab----> Msi Command-Line Arguments----> /x {4E513BB8-74A0-4626-A967-EFB85EAE9759} Alas that didn't work. When I launch the installer it says 1629 invalid command line as you can see in Scr3.jpg So now I'm puzzled and don't know where I went wrong. Thank you for your help Patrick ... View more

I hope that helps. Thanx a lot for the help but I'd need something specific. I'd really need a CHECKBOX at the side of prerequisite form so that the user can uncheck some/all of them BEFORE pressing the next button. By doing that I wouldn't have to press YES INSTALL/NO SKIP per each prerequisite. Is doing it by installscript code the only chance? :confused: ... View more

Thanx a lot Randy, I've been working thouroughly on the problem and got to the same solution. So now I know that I did well Patrick ITI_Randy wrote: There may be better options for you than having a compressed package of that size. Typically the reason for a compressed package is simply that you desire to distribute only a single file to your customer, but when it requires compressing 2 GB, it becomes impractical for both you and your customer. The project will take forever to build in your InstallShield IDE and it will take forever to unpack on the customer's target machine before the Welcome dialog appears. Another possible solution is to leave the file structure uncompressed and simply create a setup to handle the installation of the uncompressed files. Your package will build for you in seconds instead of 20 or 30 minutes and it will launch immediately for your end customer, instead of them thinking it has failed because it takes so long to start. You can do this and still distribute a single file by zipping the end result with a product like WinZip which will allow you to create a quick zip for deployment that simply unpacks your files, launches your setup, waits for it to complete and then dumps the leftovers. We have also found instances where we create a setup to handle the uncompressed files and then create a single ISO file of the structure which allows for quick easy transfer to CD/DVD or download by the customer as a single file. ...

So first of all thank u so much for your hint. That worked for me!! Any clue about the other problem, the one related with the with unknown publisher? >... another problem which is show here by Flexera as a known issue http://kb.flexerasoftware.com/selfse...rnalID=Q112476 > and here by me as a thread in the forum: http://community.flexerasoftware.com...225#post488225 Ah yes I'm using installshield spring professional 2012 on a IS-MSI project.

Thank u for your help Phill, I am pretty sure about this issue since i put some MsgBox and SdShowMsg. The former is doing fine while the other one just vanishes. The only hint is related to another problem which is show here by Flexera as a known issue http://kb.flexerasoftware.com/selfservice/viewContent.do?externalID=Q112476 and here by me as a thread in the forum: http://community.flexerasoftware.com/showthread.php?206412-Unknow-publisher-issue-on-Win8&p=488225#post488225 So could it be that SINCE THE PUBLISHER IS REPORTED AS UNKNOWN SdShowMsg COMMANDS ARE NOT EXECUTED? As for your mail I am doing nothing so weird as u can see in the example below SdShowMsg("UAC Level Change - Please wait",TRUE); if (RegDBSetKeyValueEx ("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Policies\\System", "EnableLUA", REGDB_STRING, "0", -1) < 0) then MessageBox ("RegDBSetKeyValueEx failed.", SEVERE); endif; SdShowMsg("UAC Level Change - Please wait",FALSE); any clue or workaround?
