c# - Allow Upgrade of Application -

i trying allow upgrade of application. if user installs 1.0.0 next time release version can give them 1.1.0 , can install that. overwriting | removing | replacing first version there should installed one version in control panel -> uninstall or change program.

my problems are:

if don't set product id equal * (use $(var.productid)" instead)

another version of product installed. installation of version can not continue ...

if set equal * installs new version , have 2 versions installed.

i have created simple wix application test this.

<?xml version="1.0" encoding="utf-8"?> <?define productversion="!(bind.fileversion.myassemblydll)"?> <?define upgradecode="f4d7f199-28f6-45d5-ad99-7c62938274be"?> <?define productid="{6408d956-40da-4aee-883e-5425f1562004}"?> <?define version="1.2.0"?>  <wix xmlns="http://schemas.microsoft.com/wix/2006/wi">     <product id="$(var.productid)" name="upgradetest" language="1033" version="$(var.version)" manufacturer="xxx" upgradecode="$(var.upgradecode)">         <package installerversion="200" compressed="yes" installscope="permachine" />      <!-- prevents down gradeing -->     <!-- 1 upgrade installes new version first removes old one. -->         <majorupgrade downgradeerrormessage="a newer version of [productname] installed." schedule="afterinstallexecute"/>         <mediatemplate embedcab="yes"/>          <feature id="productfeature" title="upgradetest" level="1">             <componentgroupref id="productcomponents" />         </feature>     </product>      <fragment>         <directory id="targetdir" name="sourcedir">             <directory id="programfilesfolder">                 <directory id="installfolder" name="upgradetest" />             </directory>         </directory>     </fragment>      <fragment>         <componentgroup id="productcomponents" directory="installfolder">             <!-- todo: remove comments around component element , componentref below in order add resources installer. -->              <component id="productcomponent">          <file id="product.wxs" source="product.wxs" keypath="yes" />              </component>          </componentgroup>     </fragment> </wix> 

i have been trying work several days have exhausted tutorials far 2008. appreciated.

update:

<majorupgrade allowdowngrades="no" downgradeerrormessage="a newer version of [productname] installed."   allowsameversionupgrades="no" /> 

bad: results in 2 versions in control panel.

update two:

<upgrade id ="$(var.productupgradecode)">    <upgradeversion minimum="$(var.productfullversion)" onlydetect="yes" property="newerversiondetected"/>    <upgradeversion maximum="$(var.productfullversion)" includemaximum="no" property="olderversionbeingupgraded"/> </upgrade>   <installexecutesequence>    <removeexistingproducts after="installvalidate"/> </installexecutesequence>  <condition message="a newer version of [productname] installed. if sure want downgrade, remove existing installation via programs , features.">not newerversiondetected</condition> 

bad: results in 2 versions in control panel.

the way i've done using guid upgradecode leaving id of product @ *. set reinstallation property amus reinstall product way want.

it kind of this

<product id="*"        name="yourproductname"        language="1033"        version="yourproductversion"        manufacturer="yourcompany"        upgradecode="{some-guid}">  <setproperty id="reinstallmode" value="amus" after="findrelatedproducts">installed , remove&lt;&gt;"all"</setproperty> 

for amus can refer microsoft documentation here careful, though. a value reinstall application if installed 1 has newer version. figure out characters need installer.
