X11 Windows XP/2000 Professional Compatibility Fix As users of seasonal adjustment in EViews are probably aware, EViews provides a convenient front end to the United States Census Bureau's X11 seasonal adjustment software. With EViews, you can specify a series to be seasonally adjusted using X11, and EViews will pass the data off to the Census X11 program, then return results directly into EViews. Once benefit of this method of performing X11 is that EViews users always perform their X11 procedures using programs provided by Census. A less desirable consequence of this approach is that problems with the underlying X11 programs are passed on to EViews users. One such reported problem has been an incompatibility between the Census X11 programs and Windows XP and later version of Windows 2000. The following describes a downloadable fix for this problem. Description On computers running Windows XP or later versions of Windows 2000, EViews users may find themselves unable to perform X11 frequency adjustment. When attempting to frequency adjust a series, one of the following messages is returned:
Diagnosis If you navigate to the directory where EViews is installed (typically "C:\Program Files\EViews4" or "C:\Program Files\EViews5"), you will see two executable files X11Q2.EXE and X11SS.EXE. Right-click on each file and select Properties to see the properties view of the files. Under the General tab of the properties view you should examine the "Modified" date for each file:
Files modified on these dates are not Windows XP and Windows 2000 compatible, and will have to be replaced as described below. Census has provided us with new Census X11 programs recommended for users running Windows XP and Windows 2000. Users of EViews 5 who are wondering why we did not install the new programs by default should note that the newer versions are not recommended for earlier versions of Windows. In particular, there appears to be a minor issue with Year 2000 compatibility as described below. Solution Download and unzip the contents of the following file into the EViews installation directory, overwriting the original X11 files. Step 1: Download the zip file. 0.7 MB X11 for Windows XP / Windows 2000 (zip file) 2003-02-14 Step 2: Unzip the contents of the file into your EViews directory (typically "C:\Program Files\EViews4" or "C:\Program Files\EViews5".) When prompted for whether you wish to replace the two existing files, you should click on Yes. Step 3: Verify the modification dates on the two files. Navigate to the directory where EViews is installed, then right-click on each file and select Properties. The modification dates should read:
If updating these files does not solve your problem, you should make certain that the directory name described in the error message is not excessively long (the X11 program has some problems with long directory paths), and that you have write permission to the directory. If either of these is potentially a problem, you may change the directory where EViews writes temp files by selecting Options/ File Locations... from the main EViews menu, and altering the temp file path. Note While the X11 fix for Windows XP and Windows 2000 allows users with these operating systems to run X11, it does introduce a new Year 2000 incompatibility. Data with observations after year 2000 are not correctly reported in the X11 output. This problem does not appear with the original X11 program. Accordingly users of other Windows operating systems are encouraged not to install this version. |
