Code 48 Trouble with device drivers Windows 7?

I have an Acer Aspire T180 Desktop that I have upgraded from Vista to Windows 7.

I can no longer see the DVD drive (an ATAPI DVD W DH16W1P ATA Device ) in "mycomputer" and cannot read anything with the drive.

I get a message about driver incompatibility with a code 48, but so far have been unable to find any solution on the NewTech Infosystems, acer or microsoft sites.

Cannot uninstall PaperPort 8

Original title: Can't uninstall a programs
I want to uninstall a program relating to a scanner I no longer have.  Carrying out the standard uninstall routine produces the uninstall wizard for the program which stops about halfway through and then gives the message "Fatal error during installation". 
This suggests that the software is not properly installed and thus can't be uninstalled (Catch 22).  I do not have the installation disc.  The software is Scansoft Paperport 8.05E, my OS is Windows 7.  Help please.

Calculating the “month number” associated with a given “reporting period”

On the 7th workday of each month (in which holidays are taken into account), my company closes the previous month’s financial books. 
For example, the 7th workday in July 2011 for closing June 2011’s financial books is July 12.

During a given “reporting period” (which is defined as beginning on the 7th workday of the current month and ending on the 6th workday of the following month), I need to calculate the reporting period “month number” (i.e., 1=Jan, 2=Feb, 3=Mar, etc.). 
Using the example above, if the current date >= 7/12/2011 and < 8/9/2011 (i.e., the 7th workday in August), the calculated “month number” would be 7.

I am very familiar with the WEEKDAY and WORKDAY functions, and setting up a range of cells containing the dates of holidays. 
In fact, my first attempt at devising a formula resulted in the following formula:

=IF(NOW()=6,WORKDAY(DATE(YEAR(NOW()),MONTH(NOW()),1),7,Holidays_Lookup),WORKDAY(DATE(YEAR(NOW()),MONTH(NOW()),1),6,Holidays_Lookup)),MONTH(IF(WEEKDAY(DATE(YEAR(NOW()),MONTH(NOW()),1),2)>=6,WORKDAY(DATE(YEAR(NOW()),MONTH(NOW()),1),7,Holidays_Lookup),WORKDAY(DATE(YEAR(NOW()),MONTH(NOW()),1),6,Holidays_Lookup))-28),IF(AND(NOW()>=IF(WEEKDAY(DATE(YEAR(NOW()),MONTH(NOW()),1),2)>=6,WORKDAY(DATE(YEAR(NOW()),MONTH(NOW()),1),7,Holidays_Lookup),WORKDAY(DATE(YEAR(NOW()),MONTH(NOW()),1),6,Holidays_Lookup)),NOW()=6,WORKDAY(DATE(YEAR(NOW()),MONTH(NOW())+1,1),7,Holidays_Lookup),WORKDAY(DATE(YEAR(NOW()),MONTH(NOW())+1,1),6,Holidays_Lookup))),MONTH(IF(WEEKDAY(DATE(YEAR(NOW()),MONTH(NOW()),1),2)>=6,WORKDAY(DATE(YEAR(NOW()),MONTH(NOW()),1),7,Holidays_Lookup),WORKDAY(DATE(YEAR(NOW()),MONTH(NOW()),1),6,Holidays_Lookup))),MONTH(NOW())+1))

Note: Holidays_Lookup is a named range containing all the holidays that my company observes for the current and following years.

The previous formula does work, except when the current month is January.

Can anyone devise a less complex formula that consistently yields the correct “month number” associated with a given “reporting period”?

Any assistance would be greatly appreciated.
 Thanks.

Again, the problems with aircode...
try the following:
 =IF((Month(workday(A1,-7,Holidays_Lookup))-1)>0,Month(workday(A1,-7,Holidays_Lookup))-1,12)
Note that the "-1" was originally missing on the TRUE element of the IF statement.
 
That takes care of everything except the exactly 7 days dates.
I suspect that what you are seeing is the effect of whether that date (the day) is included or excluded, analogous to the difference between < and <=
 
You'll have to decide which is technically accurate for your need, and if your original dates are the correct count, you could probably achieve the correct results by using -8 (or -6) instead of -7 to move the date range up or back a day.
Alternatively you
could play around with adding those 7th days to your holiday list, but that isn't as elegant as just shifting the number of days to match up with how Excel calculates dates.
 
HTH,
Keith

Manually editing the Windows registry

Manually editing the Windows registry to remove invalid MACHINE_CHECK_EXCEPTION keys is not recommended unless you are PC service professional. Incorrectly editing your registry can stop your PC from functioning and create irreversible damage to your operating system. In fact, one misplaced comma can prevent your PC from booting entirely!


Caution: Unless you an advanced PC user, we DO NOT recommend editing the Windows registry manually. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows. We do not guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

To manually repair your Windows registry, first you need to create a backup by exporting a portion of the registry related to MACHINE_CHECK_EXCEPTION (eg. Windows Operating System):

  • Click the Start button.
  • Type "command" in the search box... DO NOT hit ENTER yet!
  • While holding CTRL-Shift on your keyboard, hit ENTER.
  • You will be prompted with a permission dialog box.
  • Click Yes.
  • A black box will open with a blinking cursor.
  • Type "regedit" and hit ENTER.
  • In the Registry Editor, select the Error 0x9C-related key (eg. Windows Operating System) you want to back up.
  • From the File menu, choose Export.
  • In the Save In list, select the folder where you want to save the Windows Operating System backup key.
  • In the File Name box, type a name for your backup file, such as "Windows Operating System Backup".
  • In the Export Range box, be sure that "Selected branch" is selected.
  • Click Save.
  • The file is then saved with a .reg file extension.
  • You now have a backup of your MACHINE_CHECK_EXCEPTION-related registry entry.
