FAQ: MSI: While installing a bunch of msi files I am getting the following error after few msi installation. "The installation can not continue because a system reboot is pending.:. What might be the issue and how to resolve the issue.

2011-09-16T10:03:00.000+05:30

Cause
Any application can set a pending reboot flag in the operating system through a registry key. Sometimes a reboot does not clear the flag. This is what the setup is detecting.
Resolution
For XP: 1. Open Registry Editor
    1.1 Click the Start Menu > Run
    1.2 Type "regedit" without quotes.
    1.3 Click OK
2. Find the key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager"
3. Rename the "PendingFileRenameOperations" value to "PendingFileRenameOperations2"
For Vista:
1. Open Registry Editor
    1.1 Click the Start Menu
    1.2 Type "regedit" without quotes.
    1.3 Right click on RUN and select Run as administrator
2. Find the key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager"
3. Rename the "PendingFileRenameOperations" value to "PendingFileRenameOperations2"

MSI FAQ: 11. How do you install 2 MSI packages, after installation of 1st MSI the machine has to reboot and upon start of the machine 2nd MSI installation has to be triggered? Once installation of 2nd MSI is completed the User has to notify with a Message that 2 MSI Installation has been completed. How do you perform the Task? ( If 1st MSI installation has failed then 2nd MSI installation shouldn’t happen)

2011-05-04T10:52:00.000+05:30

There are multiple ways to achieve the above task. I will list two methods and I will recommend the first method as its easy, simple, less error prone and has more changes of compliance with company policy.

Method 1: Use Corporate Package Distribution System such as CA DSM (not sure about SCCM)

• Create two normal packages and then import them in CA DSM, Set the reboot after installation on the install procedure of the first package. (DO NOT LET MSI reboot itself)

• In CA DSM create a policy with install procedures of both the packages.

Isn’t is simple. What happens that when the procedure is deployed on the package first package is installed and then CA DSM reboots the machine, once the machine comes back online then the second package is installed. If the installation of first package fails then CA DSM will not install the second package. :)

Method 2: Use of Active Setup

• Create package B, add the created package in the files section of package A. Set REBOOT property to Force.

• Set active setup in package A, in the stub section add the details to silently install package B.

NOTE: PLEASE FOR GOD SAKE, do not create a nested msi or create a script which will install the msi files.

Custom Actions

1. How to add custom actions to run only during patching

Add "PATCH" To condition in custom action

2. Name few best practices for creating a Custom Actions

* Do not use custom actions in your package that require elevated privileges to run.

MISC

1. Which runs first "Run" key or Active Setup

Applications launched by Active Setup will run first. Activesetup is using to configure the userprofile settings if no entry points exists in the package and this will be running only once for a specific user.

Where as RUN key will execute everytime when user login the machine. These settings are configured with different sequence , in order to speedup to get access to windows desktop\user level settings.

2. If you extract a COM information through registering the dll or OCX file which tables will it be reflected

3 Can you elaborate the driver handling via device driver?

4 Apart from APP search what tables you use to find whether the particular application is installed via MSI tables?

5. What is the meaning of Launch condition Office2007

Only proceed the installation if value of "Office2007" property is less then "office2003" property

6. What are the attributes you set for files going under c:\Winnt\System?

Nothing, we will let Windows default file setting to be propagated to the newly added files also.

7. What happens if non-keypath file is deleted and a shortcut is launched.

Nothing Happens,

MSI SDK

1. How many tables can control the flow of Installer. Name them

6 tables,Names of them are InstallExecuteSequence, InstallUISequence, AdminExecuteSequence, AdminUISequence, AdvtExecuteSequence, AdvtUISequence

2. During typical execution how many of them are used.

Only 2 tables are used during any typical execution

MSI Sequence

1. Can we control Uninstall GUI

No.

MSI >=4.5

1. What is Per User Application (PUA)

An application capable of being installed, updated, run and removed by a standard user without elevation is called a PUA

2. What is the minimum OS on which MSI 5.0 will get installed

Windows 2008 and Windows 7

3. What is single package authoring / dual purpose package

A dual purpose package is a windows installer 5.0 package that has been authored to be capable of installing an application in either the per-user or per-machine installation context.

4. What is the limitation of PUA/DPP

TIPS: Python: Copying text in Clipboard using Python

2010-05-19T06:41:00.000+05:30

following code lets you achieve that.

TIPS: Issues while compiling WXWidgets

2010-05-08T06:17:00.000+05:30

If you have msys installed & added to the path then WxWidgets failes to compile and you will get the error which starts as follows

if not exist gcc_mswd mkdir gcc_mswd

The easiest solution to resolve is in the command prompt remove all the path folders except windows & mingw paths and then try to recompile in the same command window.

2010-03-06T09:21:00.000+05:30

Latest version of wxFormBuilder does not support wxAdditions fully, thus I have updated few XML files to support FlatNotebook & wx.propgrid widgets.

Download wx.propgrid and install it.

Download the XML.Zip folder and extract it in plugins\wxAdditions\xml folder.

Restart the wxformbuilder.

I did not tried to update these files for other widgets but it should be similar.
